Gonzalez = Same; Goes from a QB with one year of production under his belt (Cassel) to a QB with one year of production under his belt (Ryan)
Ryan = Up; Another year of maturity/familiarity plus an added weapon. He'll probably be a top-10 QB, but nowhere near 1st or 2nd round in a non-keeper.
Roddy White = Up; Fewer double teams on the rare occasions when he crosses the middle, plus another year of development from Ryan.
Michael Turner = Same; Look for a more efficient year with fewer touches but similar production. Gonzalez will help by opening up the middle of the field, plus he's a capable downfield and in-line blocker.
Matt Cassel = Down; Change of scenery, only 1 legitimate weapon (Bowe) and a shaky running game. He basically has to re-prove himself before I draft him over the likes of Aaron Rodgers, Philip Rivers, or Ryan.
Dwayne Bowe = Down; Barring any unforeseen acquisitions, he'll have a CB and Safety on his butt all year.
Kansas City's TE = Up; The cupboard is now whatever is emptier than "bare". They basically have to draft a TE early this year, and if it's a pass-catching guy such as Chase Coffman, he'd be worth at least a high 2nd round pick in a dynasty league draft.
