Interesting speculation about Murray and why he lost the Nalbandian match.
I would say that playing the net is now no longer a requirement to winning Wimbledon. I know Henman sounds like a bit of a whiner when he says it, but the grass and balls at Wimbledon have been slowed down to counteract the huge servers that have come of age in the past number of years. When the ball sits up a bit more on the grass, it is all to the benefit of a baseliner and a detriment to a server & volleyer.
Look at Lleyton Hewitt, a baseliner thru & thru and he won Wimbledon from the back court. It's not the same game even as when Sampras played. The thing is, Murray's got a glimmer of Hewitt in him when he was out there at Wimbledon and that can only be a good thing.
As for his fitness, remember that a) he's only played about 4 ATP matches and b) he was out for about 6 months in the past year from injuries. At that level you can't afford to be out for 6 weeks much less 6 months. Nalbandian was able to use this to his benefit but had this been 1 or 2 years from now it could have been a completely different result, even if it went to 5 sets again.
One thing about Henman, everyone likes to bust on him because he hasn't won a grand slam, but being #9 in the world does take loads of talent. Getting to the semifinals of a number of grand slams takes tons of talent.
I can't remember who said it but it was a good quote, "Henman is the #9 tennis player out of 6 billion people!"
