I think it was a legitimate concern...

I didn't really have it... but there are no few amount of QB's who struggle 'learning' that... at least too the level of proficiency needed in the NFL.

In fact... listening to a college coach recently he told some kids, (this was a talk about what recruiters look for, and he was talking about College D1 and not the Pros but never the less)... he said it's one of the main things they check regarding QB's.
