Just a few weeks ago, Donald Young beat Greg Jones of Australia 6-1 6-0. Greg Jones is ranked 225 in the world. Are you saying that you can do better against Donald Young than the 225-ranked player in the world?
Sort of a rhetorical question, isn't it? Don't let the tv fool you, the pace is totally different at ground level.
Let's not be so hard on the Donald. Give him another two inches and he would be a beast. I watched him practice at the Legg Mason and his ball had a nice solid thwack that comes from having a really pure stroke. There's nothing wrong with any part of his game, and his volleying is up in the top 1% of pros, I would say. He just doesn't have the size or the big weapon. And he's not 6', I'm pretty sure of that.
