Tarvaris Jackson for Brady Quinn?

The Browns are looking to deal Brady Quinn and want a quarterback in exchange.Tarvaris Jackson is essentially done in Minnesota, whether or not Brett Favre returns.So, why not?I'm not as low on Quinn as others are -- playing for that awful Cleveland team will make anyone look bad. I don't know if his 53.2% completion percentage and 5.2 yards per attempt last year were his fault of the fault of his receivers, but he avoids turnovers (just nine interceptions in 353 career attempts and four fumbles on 45 career "touches") and he just looked too good in college to be a complete NFL bust. Give him Sidney Rice, Bernard Berrian, and Visanthe Shiancoe to throw to and Adrian Peterson (and LaDanian Tomlinson?) to hand off to, and he'll have to look better.Besides, the Browns already have Seneca Wallace. With T-Jack, they could have the most mobile quarterbacking in the league, which they'll probably need.
