Thanks for this thread, it's very unique and interesting
I think it is possible they could hog all the TMS tourneys.
Roger has a huge chance to makes it 7 out of 9 this week and Rafa could win Madrid - its not that fast.
Paris will be the hard one - that's Marat territory
Also another interesting stat is that if Roger wins this week then all over the Masters-Series, Grand Slams and TMC will currently be held by 3 men.
Federer - Wimbledon, US Open, TMC, Indian Wells, Miami, Hamburg, Cincinatti
Nadal - Roland Garros, Monte Carlo, Rome, Montreal
Safin - Australian Open, Madrid, Paris
I think that would be pretty rare also
