I think that the real question is, "Who can stop Coria from winning the French?"
We should start talking about possible spoilers such as Ferrero, Gonzalez, Moya, Costa, Nalbandian, Hewitt, Guga, and all the other Spaniards and Argentines that grew up on the dirt.
However, I think that any player that plays a similar style to Coria is cooked on clay against Coria, even Ferrero. I really don't feel that Andre can win the French at this stage in his career, but he has proven me wrong in the past. I think a guy with a huge serve that ends points quickly has the "potential" to upset Coria on a good serving day. Martin Verkerk did it last year at the French. Coria should be weary of guys like Ivan Lubjicic, who has had good results on clay, or any other big serving guy. The major roadblock, in my mind, to Coria hoisting that Cup on the second Sunday of the French, is one man. The man. Roger Federer. Roger is superior to every other player on the tour, on any surface. True, clay may be the equalizer that the other players need to defuse Roger's game, but even on the dirt, when Roger is focused and fit, nobody can match his level. I will be very interested to see how Roger progresses during the clay court season, and I can't wait to diagnose his form and chances of winning, going into Roland Garros.
The way I see it, the only thing that can stop Coria now is his body or his mind. An injury would put Coria out of the money, and his body has broken down many times before. Also, if he starts believing the hype that he is invincible on clay, somebody may catch him sleeping on an off-day. He may also begin to feel the pressure of being the "man to beat" on red clay. We have seen many others fold from the pressure, but Coria doesn't seem like that type of an athlete. All I do know is that whatever scenario does play out, I will be watching, analyzing, and loving every second of the action.
