Wow, Nov 20, you're generous.
Well, since it's only April and Roger's been winless and sick for 3 months if not more, I'll say he slides to 3rd at YE.
So I got YE 2008
1. Nadal? (nah...)
2. Djokovic (surely he'll be #1)
5. Tsonga (with 1 GS F under and 0 pts at 2007 RG, he has the most to gain whereas the others have more to lose)
