i would also add that Bledsoe likes to look for deeper options, so during a max protect call his first desirable option is to a deeper pattern, or more accurately to his favorite WR Terry Glenn. Since Glenn's routes are generally mid- to long-range passes that is where Bledsoe is looking. McNabb for instance is conditioned to go to his TE or RB in their WCO, so if you plugged him in to our offense he would hit those dump passes to the RB much more often than Bledsoe does, all other things being equal.
Better to shelve some of our options than shelve our QB...
