Toni lost my respect. It's one thing to be greedy and propose any changes to suit for Nadal, but to wish his rivalries get injured so Nadal can have the whole field to himself is way out of line.
Whether or not he was the best, he was certainly the highest ranked as he held the number #1 ranking without ever winning a Slam. In contrast to the women's tour where there have been no less than 3 Slamless players to achieve the #1 ranking in recent years (Safina, Jankovic and Wozniacki) I think Rios was the only player on the men's tour to achieve the #1 ranking without ever winning a Slam, at least in the Open Era.
