Bush is having an okay year, but its only okay because hes a rookie. if he was an experienced RB, this would be a pretty ty year for someone that was so hyped up.
and Leinart can put up all the stats he wants, but without wins, its meaningless. the Cardinals are what, 1-7 with him starting? compare that to Vince Young, who has a FAR worse team surrounding him, and a tougher divison, but he has led his team to a 4-4 record.
granted, its still rookie years for these guys, and i think that Leinart will be a very good QB, but id say so far this year, that VY has accomplished more than Leinart. both have put up crappy stats, but VY has put up the wins, which is what matters most for a QB.
