Only cause Lleyton is an old crock.
Lleyton at his peak would eat guys like Simon for dinner.
Gilles barely lost games to Hewitt in their other two meetings in 2007 and 2009. I know he wasn't at his best then either, but Gilles does not have problems with players who have playing styles like Hewitt. Hewitt clearly is a much better player than Gilles at his best but I think he would have struggled against Gilles anyway.
