You have a talented RB tandem, a talented O-line, an upper tier TE, and some good (and yes, young) WRs. The defense needs some work, but you have a lot of the pieces in place, you just need to tweak them and your kicker is a solid one too.
In the 2007 draft, JaMarcus Russell got the top pick, while Brady dropped to 22 before Cleveland traded up. And since then he's played six games in three years under two systems.
People think he physically can't throw the deep ball. He's not tall enough or just not good enough. But when you have the likes of "Chud" and Mr. Daboll calling the plays, it's hard to play QB.
Now it may seem cliché because you already have two previous Cleveland QBs, but Frye would serve as a good mentor to a young QB like Quinn. Another problem: Unless the Raiders plan to draft a QB in next year's draft and take time to develop him, the Raiders are looking at either spotting talent in a later round pick or after the 2011 draft (Seymour trade).
I can honestly say that this would be a wise investment. Cleveland is cleaning house right now, and they've already burnt this bridge. Oakland passed on Quinn in 2007...should they risk passing on him again in 2009?
