Lopez is in no way a pusher, what are you talking about?
Lopez definitely does tend to push from the back of the court, more so these days than in the past, that is without a doubt. Overall, is he a pusher, no.
And rocketassist, you're kind of right, more reward should probably be placed on M1000, but Gulbis has been losing early left and right even with his new "effort". I think he'd have been far more successful if he approached tennis more like this with the game he brought when he was younger. He definitely doesn't have the same kind of pop from the back of the court. I think much of that has to do with that horrific forehand.
