On the other hand, one might also think that Roger is now convinced that 2008 will be his last chance to grab the RG title.
I got that impression too. And you can tell Roger desperately wants to win that damn thing.
I don't think adding another small tournament on clay will make a big difference for his RG. Anyway his only problem in RG for the last three years (and probably he has much more to worry about in the coming years) has been that one guy, and playing more matches on clay doesn't necessarily help him play better against that one guy.
I hope he doesn't drain his body too soon because of the energy and focus on RG.
Anyway he should worry about the next big thing-Australian Open first before he has his eyes and mind totally on RG.
