I honestly can't think why this is.
He has no trouble with flat hitting pusher/grinder type players - look at his record against Hewitt. He even has no trouble against aggressive grinders - look at his record against Davydenko. He has no trouble with moderately heavy topspin grinders like Ferrer - who has never beaten him. Only when you get into excessive topspin grinders like Nadal does Federer begin to have some trouble. And I doubt anyone would accuse Simon of hitting excessive topspin.
So why Simon? He hits a flat ball consistently to Federer's strike zone and he hardly has a slice backhand, so Federer's slice should bother Simon's two-hander. Granted, Simon doesn't miss or make mistakes, but then neither do Hewitt or Ferrer, and they both have woeful records against Federer. And they both have better movement and speed than Simon. So what is it with Simon? Simon hardly has a great net game and rarely goes up there of his own accord, so it's not like he's consistently pressuring Federer to come up with the pass. And Federer's infamous 'short slice' play should theoretically work wonders for drawing Simon out of his comfort zone and into the net.
Historically, trying to simply make Federer hit 'one-more-ball' has not been the way to beat Federer - because Federer will hit that one more ball - and it will be a winner.
So what about Simon's game gives Federer trouble?
