The brain is big in every sport, ... Andre has become a swollen brain out there. He doesn't go for winners on every ball. That's what Andy is striving to do. That's what we are striving for. He's like a piece of clay right now. I don't think it's good thing at any sport if you're too good at 21 or it's too easy. You have to keep working and keep improving and he can do that. He's 21 and he's getting better.
