I'm trying to learn to ignore those who blame or credit a team's record on the quarterback. It is such a poor way to judge a position in a team sport. And we don't do it with any other position. I mean, no one looks back on the 1989 season and blames Troy Aikman for us being 1-15. No one blames that record on starting RB Paul Palmer, either. But, of course, that's probably only because we have the benefit of hindsight and know that the problems had nothing to do with the QB, and had a lot to do with counting on too many Paul Palmers.
It seems that the only way for a QB to shake the blame that the record is his fault is if his team wins a Super Bowl, and even then that's when fans will bring up that it is a team sport, if they don't like the QB.
I don't want to take anything away from Rush for what the team accomplished, and I think there's a tendency to do that because of those who give him all the credit for it. But those who do that are either ignorant or purposely trying to push buttons. Neither of those are a good reason to discredit him IMO.
