Since it started in its current format as the NFL’s main primetime package in 2006, the defining feature of NBC’s Sunday Night Football has been the use of flexible scheduling to ensure the best matchups and showcase the best teams as the season goes along. Well, that’s the theory, anyway; the reality has not always lived up to the initial hype and has at times seemed downright mystifying. Regardless, I’m here to help you figure out what you can and can’t expect to see on Sunday nights on NBC.

A full explanation of all the factors that go into flexible scheduling decisions can be found on my NFL Flexible Scheduling Primer, but here’s the Cliffs Notes version with all the important points you need to know:

• The season can be broken down into three different periods (four if you count the first four weeks where flexible scheduling does not apply at all) for flexible scheduling purposes, each with similar yet different rules governing them: the early flex period, from weeks 5 to 10; the main flex period, from weeks 11 to 17; and week 18. In years where Christmas forces either the Sunday afternoon slate or the Sunday night game to Saturday in Week 16, flex scheduling does not apply that week, and the main flex period begins week 10.
• In all cases, only games scheduled for Sunday may be moved to Sunday night. Thursday and Monday night games are not affected by Sunday night flexible scheduling (discounting the “flexible scheduling” applied to Saturdays in December in recent years – see below).
• During the early and main flex periods, one game is “tentatively” scheduled for Sunday night and listed with the Sunday night start time of 8:20 PM ET. This game will usually remain at that start time and air on NBC, but may be flexed out for another game and moved to 1, 4:05, or 4:25 PM ET on Fox or CBS, no less than 12 days in advance of the game.
• No more than two games can be flexed to Sunday night over the course of the early flex period. If the NFL wishes to flex out a game in the early flex period twelve days in advance, CBS and Fox may elect to protect one game each from being moved to Sunday night. This is generally an emergency valve in situations where the value of the tentative game has plummeted since the schedule was announced, namely in cases of injury to a key star player.
• CBS and Fox may also each protect games, historically in five out of six weeks of the main flex period (whether or not they received an additional protection with the expansion of the main flex period an additional week is unknown), but all of those protections must be submitted after week 5, week 4 in years where the main flex period begins week 10 (so it is always six weeks before the start of the main flex period).
• No team may appear more than six times across the league’s three primetime packages on NBC, ESPN, and Fox/NFL Network, and only three teams are allowed to appear that often, with everyone else getting five. In addition, no team may appear more than four times on NBC. All teams’ number of appearances heading into this season may be seen here.
• According to the league’s official page, teams are notified when “they are no longer under consideration or eligible for a move to Sunday night.” However, they rarely make this known to the fans, and the list of each network’s protections has never officially been made public. It used to leak fairly regularly, but has not leaked since 2014.
• In all cases, the NFL is the ultimate arbiter of the schedule and consults with CBS, Fox, and NBC before moving any games to prime time. If the NFL does elect to flex out the Sunday night game, the network whose game is flexed in may receive the former tentative game, regardless of which network would “normally” air it under the “CBS=AFC, Fox=NFC” rules, keeping each network’s total number of games constant. At the same time, the NFL may also move games between 1 PM ET and 4:05/4:25 PM ET. However, this feature focuses primarily if not entirely on Sunday night flexible scheduling.
• In Week 18, the entire schedule is set on only six days notice, ensuring that NBC gets a game with playoff implications, generally a game where the winner is the division champion. More rarely, NBC may also show an intra-division game for a wild card spot, or a game where only one team wins the division with a win but doesn’t win the division with a loss, but such situations are rare and 2018 and 2020, respectively, were the first times it showed such games. If no game is guaranteed to have maximum playoff implications before Sunday night in this fashion, the league has been known not to schedule a Sunday night game at all. To ensure maximum flexibility, no protections or appearance limits apply to Week 17. The NFL also arranges the rest of the schedule such that no team playing at 4:25 PM ET (there are no 4:05 games Week 17) could have their playoff fate decided by the outcome of the 1 PM ET games, which usually means most if not all of the games with playoff implications outside Sunday night are played at 4:25 PM ET. However, beginning this season, the NFL will also move two games to Saturday to be simulcast on ESPN and ABC.

Before we begin, I have to apologize for not getting this post out last week; between that and the massive delays affecting the season-opening post this has not been my best year for the Flex Schedule Watch. I think I’m going to have to find a way to start working on the Week 15 post before the Week 15 games are over (perhaps by making a cheat sheet), or otherwise abandon the notion of giving percentage chances for each game two weeks out, especially with the 17th game a) adding a game that may or may not be common for wild card purposes and b) pushing the two-weeks-out week to the week of Christmas when I’m travelling and dealing with other commitments, and especially with my attempting to figure out if the strength of victory tiebreaker could be settled before the final week for some situations. While this post has always been the most work and the most stressful part of working on the Flex Schedule Watch since I started using ESPN’s FPI to calculate more specific percentage chances for each game, this year was particularly exhausting, stressful, and while I did manage to finish the work by the end of the day Sunday, the Sunday night game was mostly over at that point. While these are percentage chances going into the Week 16 games (click here to see what the playoff picture looked like going in), I didn’t get the predictions for the Week 17 games until late Saturday night so some of these percentages might incorporate predictions that take the results of the Thursday night and Christmas games into account, and some of these should be considered approximate as I wasn’t as exhaustive at looking at the overall playoff picture as I have in years past. With that in mind, here are the percentage chances for each game being suitable for Sunday night (not Saturday, and mostly not attempting to predict whether they’ll actually be selected) prior to the Week 16 games, along with a very brief summary of why:

Week 14 (December 12):

• Tentative game: Chicago @ Green Bay
• Prospects: 4-7 v. 9-3. At this point the Packers are more concerned about the first-round bye than the division, and the Bears may have won on Thanksgiving but that doesn’t mean they have much more to be thankful for than before.
• Likely protections: Bills-Bucs (CBS) and Cowboys-Football Team (FOX).
• Other possible games mentioned on last week’s Watch and their records: Ravens (8-3)-Browns (6-6), Raiders (6-5)-Chiefs (7-4), Niners (6-5)-Bengals (7-4), Falcons (5-6)-Panthers (5-7).
• Impact of Monday Night Football: None.
• Analysis: This may be the NFL’s oldest rivalry, but I’m still not sure the league can in good conscience give the Bears a primetime showcase, certainly against a team with a four-and-a-half-game lead over them in the standings playing at home. The thing holding back a potential flex has always been the lack of options that wouldn’t give NBC both halves of a divisional matchup, which is where the Niners’ winning streak comes in. With the win against the Vikings the Niners are now one of only two non-division-leading teams in the NFC with a winning record (which does mean the Bears are only a game out of the playoffs), and they beat the other one in a Monday night stunner at the start of the winning streak. I said such a win would cement this game’s status as one with wild card implications in both conferences, but the Bengals actually could have taken the AFC North lead if the Browns had beaten the Ravens on Sunday night. Despite all that NBC would probably still much prefer to put on Bears-Packers (which is why I hoped the new TV deal would cement MNF‘s place as a co-main primetime package where most matchups between name teams would go by returning it to ABC full-time, leaving SNF for the actual best games), so I wouldn’t be surprised if the league decided to hold off on a flex (and I might predict they would if the Bears played like you’d expect a team in playoff contention to play against a winless team), but if the league did hold off on flexing in Chargers-Bengals last week because of the possibility that it’d result in SNF travelling to Paul Brown Stadium in consecutive weeks, the one thing preventing the best-case scenario for such a move was the Bears winning a game they may have only won because the winless Lions were trying to lose. The Bears may bring some trainwreck potential, but does the league really want to risk putting on a blowout where the Bears embarrass themselves and the Packers have their way with them, or do they relieve the embarrassment of riches CBS has in the early window with the three best unprotected games?
• Final prediction: San Francisco 49ers @ Cincinnati Bengals.

Week 13 (December 5):

• Tentative game: San Francisco @ Seattle
• Prospects: 5-5 v. 3-7. These teams have officially started moving in opposite directions, and while the Seahawks have played good teams since getting Russell Wilson back, there’s some sense that the most recent loss represented the door shutting on their playoff chances.
• Likely protections: Ravens-Steelers (CBS) and Cardinals-Bears, Bucs-Falcons, or nothing (FOX).
• Other possible games mentioned on last week’s Watch and their records: Chargers (6-4)-Bengals (6-4), Broncos (5-5)-Chiefs (7-4), Bucs (6-3)-Falcons (4-6).
• Impact of Monday Night Football: None.
• Analysis: There’s less of a sense that these are the wrong two teams in the NFC West than there was before, but only because the Niners are starting to make the game look lopsided. Against a better opponent the tentative game bias might favor the Niners, but as it stands Chargers-Bengals has a pair of pretty good records and a decent storyline with two hot young QBs squaring off. I wouldn’t be too surprised if Broncos-Chiefs was picked or even if the game kept its spot, but there’s a clear favorite for me here.
• Final prediction: Los Angeles Chargers @ Cincinnati Bengals.

Week 15 (December 18):

• Tentative game: None (2 games to be moved to Saturday).
• Possible games: Jets (2-8)-Dolphins (4-7), RedHogs (4-6)-Eagles (5-6), Raiders (5-5)-Browns (6-5), Panthers (5-6)-Bills (6-4), Patriots (7-4)-Colts (6-5).
• Impact of Monday Night Football: None.
• Analysis: Two of the 5-5 teams won to create two matchups of teams at or above .500, and they were the games I had thought had the most name value. The Panthers are not a terrible team and the quality of their game might be close to on par with Raiders-Browns, but I’m not sure how compelling they’ll be for the league.
• Final prediction: New England Patriots @ Indianapolis Colts and Las Vegas Raiders @ Cleveland Browns.

This game will usually remain at that start time and air on NBC, but may be flexed out for another game and moved to 1, 4:05, or 4:25 PM ET on Fox or CBS, no less than 12 days in advance of the game.
• No more than two games can be flexed to Sunday night over the course of the early flex period. If the NFL wishes to flex out a game in the early flex period twelve days in advance, CBS and Fox may elect to protect one game each from being moved to Sunday night. This is generally an emergency valve in situations where the value of the tentative game has plummeted since the schedule was announced, namely in cases of injury to a key star player.
• CBS and Fox may also each protect games, historically in five out of six weeks of the main flex period (whether or not they received an additional protection with the expansion of the main flex period an additional week is unknown), but all of those protections must be submitted after week 5, week 4 in years where the main flex period begins week 10 (so it is always six weeks before the start of the main flex period).
• No team may appear more than six times across the league’s three primetime packages on NBC, ESPN, and Fox/NFL Network, and only three teams are allowed to appear that often, with everyone else getting five. In addition, no team may appear more than four times on NBC. All teams’ number of appearances heading into this season may be seen here.
• According to the league’s official page, teams are notified when “they are no longer under consideration or eligible for a move to Sunday night.” However, they rarely make this known to the fans, and the list of each network’s protections has never officially been made public. It used to leak fairly regularly, but has not leaked since 2014.
• In all cases, the NFL is the ultimate arbiter of the schedule and consults with CBS, Fox, and NBC before moving any games to prime time. If the NFL does elect to flex out the Sunday night game, the network whose game is flexed in may receive the former tentative game, regardless of which network would “normally” air it under the “CBS=AFC, Fox=NFC” rules, keeping each network’s total number of games constant. At the same time, the NFL may also move games between 1 PM ET and 4:05/4:25 PM ET. However, this feature focuses primarily if not entirely on Sunday night flexible scheduling.
• In Week 18, the entire schedule is set on only six days notice, ensuring that NBC gets a game with playoff implications, generally a game where the winner is the division champion. More rarely, NBC may also show an intra-division game for a wild card spot, or a game where only one team wins the division with a win but doesn’t win the division with a loss, but such situations are rare and 2018 and 2020, respectively, were the first times it showed such games. If no game is guaranteed to have maximum playoff implications before Sunday night in this fashion, the league has been known not to schedule a Sunday night game at all. To ensure maximum flexibility, no protections or appearance limits apply to Week 17. The NFL also arranges the rest of the schedule such that no team playing at 4:25 PM ET (there are no 4:05 games Week 17) could have their playoff fate decided by the outcome of the 1 PM ET games, which usually means most if not all of the games with playoff implications outside Sunday night are played at 4:25 PM ET. However, beginning this season, the NFL will also move two games to Saturday to be simulcast on ESPN and ABC.

Here are the current tentatively-scheduled games and my predictions:
