Just a thought but if this is the way the league is going, by extending the regular season while increasing the amount of play off teams. How long until we see NBA style Load management be implemented in the NFL?
Think about it by Week 15 you've already got a bunch of guys banged up, say the #1 seed in your conference is clinched already.. what's to stop teams from just resting their key stars for the last 3-4 weeks of the regular season, or playing them sparingly to get 1-2 series of reps and just preserve them for the playoffs if the best you can do is a 4-7 seed.
These could be some of the "unintended consequences" of adding regular season games, and diluting the Playoff pool.
