I'll be pleasantly surprised if Perry ends up balling out, but, in my life experience, people don't change. You are who you are, and who you are is who you always will be.
Despite what they want, or how badly they want it, fat people usually don't lose weight, lazy people usually don't become millionaires, stupid people usually don't become educated, etc. You are what you are, and no **** coach is going to change that.
Perry is the kind of person who makes bad decisions on and off the field, and doesn't work hard in the film room during the offseason.
If Perry starts, he'll be exactly the same QB this year as he was last year, and he will let us down. That's my prediction. We'll see if I'm right.
