I'll start off by saying I don't think Dontrelle will be great, but a decent #3 starter, and nothing more. He shoudl be excellent trade bait in early-mid May though.
And about Prior being a role model by Cornbread's requirements, I seem to remember him being cocky and arrogant last season. I just can't remember the exact time-frame or reason. Maybe he's a good guy, because I havn't heard him talk at press conferances or anything, I'm just basing this on one or two instances I heard last year.
And I don't personally see anything wrong with being cocky as long as you aren't degrading somebody you beat. If you say your the best, and you are, that's fine. I don't see how that has a negative influence on kids. People that no matter what, have an excuse for why they didn't win, an excuse for why somebody else won, etc, are bad role models IMO. I can't stand those people in real life. Everything bad is somebody elses fault, and everything good couldn't have happened without them.
