First, his upsides. He's definitely smarter than some past QB busts. Ryan Leaf comes to mind. He's very kind to his family and teammates, so his reforms should start there. I think all it will take is determination and a great mentor.
He has plenty of determination. The question is whether he has a good mentor. Is Lovie Smith a good mentor for him? I think so. He's a good leader who in a lot of ways reminds me of Tony Dungy. I'm not sure, but I think he'll help.
So, yes, I think Winston has a good chance of turning it around. I really hope so, and if he does, the Bucs will make the playoffs.
