Rams got a ton of talent and of course if they play their best game every week they are as good as any, but I just won't believe that in Matt Stafford in the playoffs until I see it happen. He knew full well he was put into a Brady-like position this year and at times he's let that pressure get to him this year with some games he really single handedly lost with his arm.
Honestly, at this point in the playoffs almost every team is capable of doing something if they play their best game. The team I find least complete is, ironically the AFC's one seed in Tennessee - not because of Tannehill, but just because with or without Henry there aren't enough passing weapons.
