Hey Green Mile, What is it about Simon's game that you like so much? Just curious. I enjoyed his stint in the top 10 a lot.
There are many different attributes about Simon's game that I like. He's got so many layers to his game, and you'll see it against varying opponents, the way he goes about his business on the tennis court. Confidence is also a big contributing factor, and the surfaces all play a part obviously.
On one hand, I like watching him grind out and outmaneuver his opponents with superior movement, his defensive capabilities, anticipation and general understanding and awareness of court geometry. The discipline he can show in a match at times is astounding. It's almost hypnotizing. I've witnessed far too many meltdowns from players that have suffered at the hands of Simon, as they try to hit through him more, as they end up rushing points and spraying copious amounts of unforced errors. And to be frank, I love it. I love watching it, his opponents throwing temper tantrums, smashing racquets, because they can't break him down.
On the other hand, when he's playing particularly well, he has that ability to inject massive pace off both wings and take his opponents by surprise, better than majority of players on tour. Probably one of the best I've ever seen at wrong footing opponents, and/or putting them off balance. He'll even employ more net game, though that's an area where he has always struggled with. He's alright at dealing with weaker balls at the net, especially off the forehand volley, but when the ball is struck even at half pace, he usually fumbles the volley unfortunately.
He's a fighter, and he's had many epic matches where he's looking seemingly out of it, only to come back and win in ridiculous fashion. Not to mention, I find his game also very aesthetically pleasing.
It's depressing watching Simon this year, when you've followed him very closely since the AO way back in 2006 where I first saw him defeat Berdych in the 2nd round, though I hope to see him go deep in a few more tournaments when all is said and done.
