Nobody is going to beat New Orleans except themselves. I don't think they will rest anybody because Minnesota is right behind them, and they both want home field advantage. Their schedule is favourable.
Washington
@ Atlanta
Dallas
Tampa Bay
@ Carolina
They have a short week to prepare for Washington, but that shouldn't be a problem. They won't lose to Dallas at home, and they already whooped Atlanta. Tampa Bay may be a trap game, as they look ahead to Carolina for the perfect season. The Saints play big in big games. 16-0
Indy has a favourable schedule as well.
Tennessee
Denver
@ Jacksonville
NY Jets
@ Buffalo
Tenneseee is lighting it up right now, but can they beat Indy in Indy? I doubt it. Manning isn't going to lose a close game this season, and the Titans don't have the firepower to blow Indy out or the D to keep Indy off the score board.
Denver has some impressive victories this year. New England, Dallas, NY Giants, San Diego and Cincinnati. They could certainly pull the upset in Indy, and since Indy is already 3 games up on the rest of the division leaders, Caldwell might be resting key players down the stretch.
I want to see 2 undefeated teams go at it in Miami for the Super Bowl, but San Diego is going to beat New Orleans, and get their Thank You card from the 72' Dolphins.
