The NFL flexed the Chicago@Philly game into Sunday night for Week 16.
There's actually at least one scenario (pending the outcome of the other Week 15 and Week 16 games) by which it's already decided going into that game that the game is meaningless from a playoff perspective for Philly*, that they're out of wildcard contention, and that their only path into the playoffs is beating Dallas in Week 17 to win the NFC East.
So the NFL's move to put that game in primetime could potentially blow up in their face, if Philly is playing for nothing, and plays conservative with its starters to protect them from injury, looking ahead to the actually meaningful game against Dallas the following week.
I actually can't remember any previous years in which a team played a meaningless game in Week 16, before a meaningful game in Week 17, but I'm sure it's happened.
* This assumes that they don't care much whether they're the #3 or #4 seed…..which most teams don't seem to care much about, and which usually doesn't affect how many home games you have, though I guess the 2006 AFC playoffs would be one exception.
Looks like there's a very good chance of this scenario coming to pass. If Dallas wins its game against Washington next Sunday afternoon, then Philly will go into the Sunday night game against Chicago knowing that whether or not they win will have no bearing on whether they make the playoffs, since their only path into the playoffs is to win the East, which they could then only do by beating Dallas in the season finale.
So all they'd be playing for against Chicago is the possibility of being the #3 seed rather than the #4 seed, which might not even be much of a bonus depending on who their wild card opponents might be. In that case, there won't be much incentive for Philly to go all out in a game that doesn't mean very much for them. Kelly presumably won't hesitate to pull the starters if the game starts to get lopsided.
Is it to late for them to flex in another game? Either way, there are games that are more important for the playoffs than the Lions-Bears bearth.
When the NFL and the networks made the "flex" agreement for the schedules, one of the provisions was that during the lifetime of the contracts, the gap between the number of games flexed from CBS and FOX could be no greater than three. The NFL always wants the last Sunday night game of the season to be one of the most importance, so they want to be able to flex either a CBS or a FOX game for that evening -- if they took one from CBS, they'd only be able to get a FOX game for Week 17.
