LOL..sounds like the guy I play with. He does all of those things, but he is such a cool dude, and a good player, it doesnt bother me. He basically taught me how to beat him and as a result, I became a better player. Takes a lot of time, fitness and hitting.
People think they are better than they are in tennis. that is the main problem. You have to go out there not caring about those things to truly play loose.
