I think Ryan Harrison has a weak backhand, a so so forehand, and his serve is not that big. I think Ryan has good hands though and he volleys well. I think Ryan just needs more discipline, I think he's letting the media attention get to him. But I also think some people are harsh, the kid is only twenty he's got plenty of time to mature. Hopefully in the next few years Harrison will be in the top 50 or higher. Harrison has got talent but I think he needs better coaching and more discipline. Ryan needs to fix his weaknesses such as his backhand he doesn't hit many winners off that side. If Ryan can improve the backhand maybe change it he can rise up the rankings.
