I remember reading on these forums somewhere there are plenty of elite QB's who had subpar rookie years so I'm not too worried.
The article also compared Sanchez's rookie season to Troy Aikman's (three Super Bowls). Anyway, a quarterback's rookie season means nothing. Usually whether or not a quarterback survives his sophomore slump tells you whether or not he'll have a good career.
Only numbers on there that I care about Super Bowl Contender (11+): 39% Thats a number I sure dont mind seeing
