So you need to decide on your argument here, are you saying Llodra is the best S&V/net rushing player on tour? According the rankings he's not...he's behind Stepanek.
If you are saying he has the best vollies, I disagree and I think players like Federer, Haas, Nalbandian, Tsonga, Mardy Fish have vollies that are just as good if not better.
When discussing the enigma that is Michael Llodra, there are many things that has to be said. Llodra only shows up for around half of the singles tournaments he plays. He is well known for his tanking, retiring and maybe even a fix or two.
Regarding his game, all the players you compare him with are vastly superior in every element besides serve, volley and touch. Stepanek is by no means a pure S&V player. Throughout a season, I am sure he does this on less than 30% of his service points. I would say Llodra follows in on around 70% of his. (Including second serve.)
On the singles tour, he is the best volleyer. Others can probably finish of a an easy put-away as good as him, but no one can dig up so many low half-volleys and cover the net as well as he does.
He is, along with Mahut to a lesser degree, the last of his kind. "The last samurai" as he was named in an older thread.
When he calls it a day and begins his new career as a sommelier, tennis will miss him.
That is of course just my opinion, but the players did pick him in the Miami perfect player thingy.
