re: Why does Petty play so poorly on the road?

no he does not suck. No it's not because of lack of mental toughness... I think something is going on with him that's affecting his performance on the road. I've coached players where they would play well on certain courts, and then they would struggle week later. Petty is used to having folks cheering for him at home and on the road when he was in HS. College is completely different and he's struggling to adjust to that. Just let him deal with it and he'll be fine.
