Call me Captain Obvious, but Brett Favre is going to take a tremendous step back this season. Given that he's coming off a career year, is a stinkin' granddaddy (read: he's old), and two of his top receiving targets have serious health concerns it's certainly not hard to predict his fall.
That's not even taking into account "the ankle", which has already had to receive injections of lubricant.
It's not to say that he, or any of the other players listed in this article won't be important contributors on their teams. I do expect their big plays to decline along with the numbers, although the two don't necessarily go hand in hand.
I'm not personally attacking any of the players mentioned, I'm actually a fan of most. In most instances it's through circumstance rather than any fault of the player that I have them on the precipice facing a steep decline.
Hopefully I present my case well enough not to offend too many fans, let's get on with the show.
