Dude you have no clue about the NFL. Sure there is minimal momentum, but it's not like baseball where you carry momentum to another game. Everyone in the NFL plays every game at 100%. Doesn't matter if you're the Jets or Niners, you go out there to win cause you may only get 16 chances to impress someone.
Wow, you are so clueless. So a team doesn't get any better or worse as the season progresses? Are you kidding me?
