I have no interest in Blough, whatsoever.
The interest in Boyle is that he has the arm, but can't get past his mistakes. They're hoping to "coach him up"... because you can't teach NFL arm strength to Blough, he just doesn't have it.
I understand the reasoning for choosing Boyle over Blough perfectly... but, you know, still... ewww!
The correct solution is to find a developmental QB that can develop at least into a backup QB, if not an actual starter. I have no problem with Boyle if the team thinks they can actually coach him up to that level. I just don't think Boyle is that guy. I'd like them to find someone better.
Sudfeld is at least a competent backup QB. That's the level of practice squad QB I'd like to see, a young raw guy who can actually be coached up to at least that level (I do NOT believe that that is Boyle).
