Note: This post does not incorporate the result of the Thursday night game… mostly. See the Week 13 section for how late-breaking news could affect flex decisions in the very near term.
On Tuesday 49ers beat reporter Matt Maiocco tweeted that Fox “plans to protect” the Week 13 Niners-Eagles game. This was noteworthy not so much for the news itself – considering the game was already slated to be Fox’s lead late doubleheader game even before last year’s NFC Championship Game participants became the last two unbeaten teams in the league and remain the top two teams in the conference, it was pretty much an inevitability – as the timing of the tweet, coupled with the “plans to protect” phrasing indicating that Fox hadn’t already done so.
Based on my reading of the words of Mike North and Michael Mulvihill – especially North’s claim that CBS and Fox submit protections “before we even start to think about” flexing out games – I had figured that while protections in the main flex period were no longer due in Week 5, they weren’t necessarily due at the same time the league needed to make the decision like with the early flex. At minimum, I figured that with TNF flexing in place, protections in the main flex period had to kick in at the same time as the deadline for that, five weeks in advance. But if Fox only “plan[ned] to protect” Niners-Eagles now, less than 19 days before game time, that suggests that the deadline for protections is no earlier than three weeks in advance, and more likely runs right up to the point where the league itself needs to make a decision.
I don’t know how this interacts with the TNF flex, though it is notable that the league’s contracts with CBS and Fox were negotiated without any assumption that the TNF flex (still first publicly floated less than a year ago) would be a thing, and recent history has shown that the NFL prefers to make sure all three of the Sunday afternoon windows – the early doubleheader as well as the singleheader and late DH – have at least half-decent games anchoring them even though the doubleheader network still has only one protection, so CBS and Fox could well be protected against losing games that are too good without any formal protections at all, especially given the restrictions on what games can be flexed into TNF. But that seems doubtful, so does this mean the league can force CBS and Fox to protect games earlier than they’d otherwise like by floating the possibility of a TNF flex, or does it mean CBS and Fox can change what game they elect to protect, so they can protect one game from TNF and another game from SNF and MNF even if the game protected from TNF isn’t in the running to be flexed in? And how does this interact with the six-day SNF flex, do networks still need to protect games two weeks in advance or can they still do it right up until a decision has to be made?
I’m going to keep waiting on any more clarification on how protection works now before committing to any changes to the Flex Schedule Watch until the start of next season’s Watch, and I’m actually still going to adhere to the five-week window for the remainder of this season, but absent any further information I am going to work under the assumption of a two-week protection window starting next season, without any firm protection commitments associated with the TNF flex.
How NFL flexible scheduling works: (see also the NFL’s own page on flex schedule procedures)
- Up to two games in Weeks 5-10 (the “early flex” period), and any number of games from Week 11 onward, may be flexed into Sunday Night Football. Any number of games from Week 12 onward may be flexed into Monday Night Football, and up to two games from Week 13 onward may be flexed into Thursday Night Football. In addition, in select weeks in December a number of games may be listed as “TBD”, with two or three of those games being assigned to be played on Saturday. Note that I only cover early flexes if a star player on one of the teams is injured.
- Only games scheduled for Sunday afternoon, or set aside for a potential move to Saturday, may be flexed into one of the flex-eligible windows – not existing primetime games or games in other standalone windows. The game currently listed in the flex-eligible window will take the flexed-in game’s space on the Sunday afternoon slate, generally on the network that the flexed-in game was originally scheduled for. The league may also move Sunday afternoon games between 1 PM ET and 4:05 or 4:25 PM ET.
- Thursday Night Football flex moves must be announced 28 days in advance. Sunday and Monday Night Football moves must be announced 12 days in advance, except for Sunday night games in Week 14 onward, which can be announced at any point up until 6 days in advance.
- CBS and Fox have the right to protect one game each per week, among the games scheduled for their networks, from being flexed into primetime windows. During the early flex period, they may protect games at any point once the league tells them they’re thinking of pulling the flex. It’s not known when they must protect games in the main flex period, only that it’s “significantly closer to each game date” relative to the old deadline of Week 5. My assumption is that protections are due five weeks in advance, in accordance with the 28-day deadline for TNF flexes. Protections have never been officially publicized, and have not leaked en masse since 2014, so can only be speculated on.
- Supposedly, CBS and Fox are also guaranteed one half of each division rivalry. Notably, some Week 18 games (see below) have their other halves scheduled for the other conference’s network, though none are scheduled for primetime.
- No team may appear more than seven times in primetime windows – six scheduled before the season plus one flexed in. This appears to consider only the actual time the game is played; Amazon’s Black Friday game does not count even though the rest of their TNF slate does, and NBC’s Saturday afternoon game Week 16 doesn’t count but their Peacock game that night does. This post contains a list of all teams’ primetime appearances entering the season.
- Teams may play no more than two Thursday games following Sunday games, and (apparently) no more than one of them can be on the road.
- In Week 18 the entire schedule, consisting entirely of games between divisional opponents, is set on six days’ notice, usually during the previous week’s Sunday night game. One game will be scheduled for Sunday night, usually a game that decides who wins the division, a game where the winner is guaranteed to make the playoffs while the loser is out, or a game where one team makes the playoffs with a win but falls behind the winner of another game, and thus loses the division and/or misses the playoffs, with a loss. Two more games with playoff implications are scheduled for Saturday on ABC and ESPN, with the remaining games doled out to CBS and Fox on Sunday afternoon, with the league generally trying to maximize what each team has to play for. Protections and appearance limits do not apply to Week 18.
