On offense, I'll go with CJ. To me, he's nothing more than an Eric Metcalf/Reggie Bush-type player. For all the hype about his speed and elusiveness, he can't hold a candle to Freddie J.
On defense, it's Kyle Williams. If he were to get down to about 270 lbs, he'd make a great MLB. But as a DT, he's so fixated on disrupting a play in the backfield that he puts himself out of position.
Call me crazy, but that's what I see.
