Carr drafted in 2002 and Boller in 2003. Both guys came out of college with all the tools and size to be successful. Both QB's thrown into an offensive situation where failure was the only option. These two QB's were like rag dolls in their first few years. The difference between the two is Carr has more confidence today. I have seen Carr play a few times in the last couple years and he doesn't have the bad jitter feet like Boller has now. Taking so many sacks can ruin your mentality. It's my belief that Carr can still contribute. On the other hand, Boller will never recover (he got knocked around in St Louis big time).
