Mustard, I know it's conventional thought to say Rios underachieved given his high talent level. But for a small guy from a weak tennis nation I think he did quite well for himself. Nobody who saw Rios early in his career, like the French Open debut vs. Sampras, had the vision to call Rios a future #1. Yet he did it. Spadea could very well be right here.
