Homer alert..
This is coming from someone who bleeds purple and roots for all our players.
What you see with Boller is what you get. IMO, he is not going to get any better. He isn't underrated, he shouldn't be rated at all.
Pros: Tough, strong arm
Cons: Doesn't see the field well, not accurate.
I don't think Smith is any better, but he has a different skill set that might fit better with the current group of players. His arm is okay, but he needs work on throwing the outs. He has leadership skills (some people refer to this as the "it" factor) and escapablity that Boller doesn't have.
I would love for Kyle to just turn the switch and prove everyone wrong. He has taken a lot of undeserved heat in his time here, and by all accounts has acted like a true professional. The problem is, it's just never going to happen.
