Because in the era of Madden videogame football coaches are no longer interested in developing talent. If you are a QB being drafted in todays NFL, if you don't play in a pro system right away you are at a severe disadvantage. Terrell Pryor is a considerable talent and in the few snaps I've seen him play he had a lot of upside, but the Raiders don't know talent if it kicked them in the face. Had they actually tried to coach him up last year, they may have become a solid starter, as opposed to the damaged goods that is Carson Palmer.
Funny thing is anytime I`ve even seen Pryor complete a pass is on Madden.
Anyone who uses the Raiders in Madden usses Pryor haha
