You will never see me writing these things:
1. Novak is not winning the CYGS this year.
2. Novak will never win more than X number of slams.
3. Novak is only a tier 2 player.
I don't like having to eat crow.
I'm saying this: getting 3 slams in a year is a rare thing in men's tennis. But it has been done. No one expected Fed to do it three times.
In 2005 he dropped to 2 slams and did not make the finals again. When he only won one slam in 2008, I'm sure people said, "That's it." Then he won 2 more the next year.
The only thing I know for sure about these great players is what they have already done, not what they will do.
The only thing I feel pretty confident about is Novak's getting to 10 or more slams. I'll be shocked if this does not happen. But I won't be shocked if he wins more.
