I think the OP is being harsh given the fact Ryan Harrison is only twenty one years old. To attack a twenty one year old is really harsh the guy is VERY YOUNG.
I don't think anyone said Harrison was going to become a champion or a top ten player. I did however, thought Harrison would have cracked the top 50 by now I am surprised he hasn't. I think it has to do with the fact Harrison does NOT HAVE ANY POWER in his game.
The serve is very inconsistent he can't seem to control the serve. Harrison seems to think serving big wins matches and it doesn't. Serving SMART wins matches he tries to hit the kick serve but he doesn't have the upper body strength to hit it properly.
However, I do feel Harrison got a lot of press in the United States because he's young, and he's a good looking young American guy.
Harrison has the potential to be a male model if his tennis career ever doesn't work out I can see him doing well in modeling if he chooses to go in that direction.
Harrison is the best looking American male player EVER he definitely has a lot of sex appeal but the problem is he hasn't translated it into tennis results.
Harrison has a sense of entitlement which some young kids get when they get their first burst of fame. Harrison needs to realize the USA media will treat him just like they did Melanie Oudin they will move on the next big thing.
Harrison needs an attitude adjustment, and he also really needs help in terms of strategy, and also with his mental approach to the game.
I think Harrison also needs better coaching, I don't know if tennis pros change their strokes but he definitely needs to change some of his groundstrokes.
Harrison's problems are technical his backhand is really poor and players attack it all the time. The forehand is strange, Harrison slaps the forehand he doesn't penetrate and hit through the ball.
Also, Harrison is not a big man he's probably six feet exactly and he's very slim he doesn't seem to have the upper body strength yet to hit a good kick serve nor does he have the strength to endure long matches.
