Hall of Fame
Difficult to pick an overall year. 2006 had his best Rome and MC appearances. I wouldn't have RG 2006 as his best though. Maybe a little better in 05 and 07. Better finals performance in 2009.
A shame he didn't play Hamburg. Still tired out from Rome. That's the one clay court where I would have favoured him against Nadal.
Maybe 2006 overall in that he didn't have any weaker performances (MC in 05, Rome in 07, MC in 09)
