Allow me to say it: HE'S NOT a #1.

Yes, even #1s like Chad Johnson suck on occassion. But he's great on a regular basis.
Berrian is great (not really, more like very good) on occasion and makes too many mistakes on regular basis.

He's still the closest thing to a Number One on the team, and the team is better with him than without him.

Adrian Peterson appears to be a better overall back than Cedric Benson, and the team would be worse without him, but that doesn't mean I want him as my starter next year.
Don't accept the mediocrity of Bernard Berrian and mistake it for true #1 ability just because the other receivers on the team suck.
There's a certain team in the NFL this year that replaced all 3 of their top 3 receivers from last year because the one's they had last year were just average...that team is the New England Patriots. It doesn't hurt to have Tom Brady, but you can't tell me that the receivers, truly good receivers, don't make a difference. And you can't tell me that you can't replace them all in one year.
