But I do assume you play tennis, right?
Hard hitter is not just hitting hard, but going for placements.
Pusher is not hitting hard, and only going for GENERAL placement, like forehand side or backhand side, not hitting close to lines.
You KNOW this is true of most pushers. Pusher are that way because they choose to play it SAFE. Safe is not going for lines.
Hitters don't play safe, because they want to hit winners.
Now look at the top 500 ATP pros. How many can you call pushers? I'll give you maybe 30. Out of 500.
