A lot of football fans liked Russell Wilson, coming out of college. He suffered the Drew Brees fate. Guy was the goods at NC State and Wisconsin. But being that he was 5'11" one-track-minded "experts" tried to write him off when he clearly was good enough to play in the league. Vick and Manziel both went in the first round, and were 6' and 5'11" respectively but hype put Manziel in round one. Vick had a cannon arm and phyisically could make every throw but, relied too much on scrambling. Manziel is just average all across the board.
Brees and Russell are both pure passers, always look to make a play with their arms but, teams always want excitement, which bites them in the backside when you simply need a passer who can throw every pass, stay healthy, and not make huge mental blunders.
