ryan Harrison, out of Texas, trained by his father, tough, still a cry baby though, throws his racquet, temper costs him, if
he ever gets it under control, will be tough..
I'm a big McEnroe fan, but Sampras, Agassi and Connors all had more Grand Slams. Sampras had twice as many. That being said, I much preferred watching McEnroe in his prime to Sampras.
Those three lasted much longer but for about five years, McEnroe was better than anyone except Federer. Don't think Sampras would have been near as goog in an era when you couldn't just serve your way out of trouble.
