I've been watching the guy occasionally and... Even from my limited viewpoint, he doesn't have a lot going for him. He's got a big cannon serve. A typically inconsistent cannon serve. Then, for the most part, it looks extremely flat, too. He's not giving himself much time to get to net. Which I think is the main reason people call him "lazy" at the net. He's not giving himself time, and gets in too many awkward positions. Not to mention the faces he makes when he hits the ball, but I dunno if it hurts his game. Hurts my eyes, though. So while I love how he moves to net...I don't think he's going very far. What HAS Dent done? He doesn't seem to really stand out.
