This guy to me seems like such a talented player...sometimes I wonder why he hasn't gotten more out of his potential. I know he's a real risk-taker and sometimes plays a little too aggressive. But I wonder if this guy received better coaching (like a Brad Gilbert-type)....could he compete with the Roddicks and Federers? He has a real presence on the court, moves well, very athletic, powerful ground game, nice serve. Consistency seems to allude him though. What do you guys think?
