Sure there are. That pusher guy who hangs around the ATP tour trying to win a point is one.
To YOU, there are no 5.0 or 6.0 pushers.
To Nadal, Fed, and most of the top 10, there are plenty of 7.0 pushers.
BradGilbert is proud to be a 7.0 pusher at times. HaroldSolomon SAID he was a pusher.
To a beginner, a 3.5 pusher is a great player who hits hard. Maybe to you also.
It depends on where you're coming from.
