Re: Four individual GS winners in 2012, not since 2003.
Now WTF decides who is player of the year.
Top 4 are pretty close if we look what happened on big tournaments
Djokovic - 1 slam, 2 slam finals
Murray - 1 slam, 1 slam final, Olympic gold.
Federer- 1 slam,Olympic silver
Nadal- 1 slam, 1 slam final
Whoever grabs WTF, is a champ. Even if he is not year end # 1
For example,if Murray wins WTF, and Fed is year end # 1, Murray would still be moral winner of the year IMO.
