To the people touting Tsonga's superior over Roddick, I wish to point out that Roddick has won a Grand Slam title, Tsonga none, Roddick has a career-high ranking of one, Tsonga seven, Roddick has been to five Grand Slam finals, Tsonga one, and Roddick has won 30 career titles, Tsonga seven. Tsonga is younger than Roddick, but it would take a positively freakish uptick in the quality of his results for him to even come close to touching Roddick. This is not a coincidence; on the whole, Roddick is clearly a superior tennis player to Tsonga.
Furthermore, were Roddick "all serve," he would have had a career like that of Ivo Karlovic, who has an even better serve than Roddick, but has only won four career titles and has never ranked in the top 10. The fact is that people tend to caricature Roddick by acknowledging the greatness of his serve, then devaluing his other attributes in a plainly unreasonable fashion. At least when fit and in-form (he was well below his historical standard this season), Roddick is a very good defender (it is no coincidence he's been a regular in the Mercedes-Benz plays of the week over the years) and is capable of outrallying the vast majority of ATP professionals from the baseline (that this is often through extremely conservative play with very few winners DOES NOT nullify this fact). In his early days, he was also a tremendous power player from the back-court, regularly delivering 100-mile-per-hour or faster forehands and showing the ability to overpower most anyone from the back of the court- see the first set of the 2004 Wimbledon final for a good demonstration. Even in the latter portion of his career, he has shown the ability on rare occasions to snap out of his defensive mindset and deliver compelling aggression, as in his win over Nadal last year at Miami.
Tsonga is a very flamboyant and spectacular player, and while he locked in, he can look positively tremendous in every aspect of the game, but this style is unsustainable, and he tends to alternate between dominating performance and ugly, losing play which gifts opponents sets and matches.
