2001- a GOAT was born, upsetting the 7-time champion in dramatic fashion. The new type of grass introduced at Wimbledon this year had no effect upon the result.
In 2008 Nadull fluked his first Wimbledon from slow grass & dark clouds over his opponents side of the court. He had also benefited from the selective darkening in the 2005 RG SF although the GOAT eyeballs had adapted by the 2011 RG SF where there were no complaints.
In 2009 however Wimbledon grass was sped back up to 2003-2005 levels and Federer finally recieved a worthy opponent in Andy Roddick.
The grass was slow as molasses again in 2010, enabling the topspin moonballer Tomas Berdych to upset the deserving champion and reach the finals.
Throughout all this, the speed of the clay courts has never been altered, and the court speed in RG 2009 was identical to that of the 1995 tournament.
The grass was changed in 2002, the GOATness of the GOAT though allowed him to still win 7 Wimbys and beat Nadal twice on the green clay.
Did No2e (or anyone) say it was too dark in that semi in '11? I can't remember. It certainly was very dark for tennis in 08 final though, as represented by the near pitch black conditions 15 minutes after MP with Nadal getting photographed on court.
Why does the clay court speed of RG 2009 matter if the only reason Nadal lost was bc he was injured?
