Player evolution: Pusher vs. Ballbasher
At the lower rec levels you see both extremes: pushers that are content to keep the ball in play and wait for their opponents to make mistakes vs. ball bashers that think they're better than they are, and try to go for broke on every shot. Neither mindset is conducive to great tennis, but which one is easier to correct and shape into a good player? I'd be particularly interested to hear from coaches.
As you can probably guess from my username, I'm on the "pushy" end of the spectrum, although I've been trying to improve at seizing the initiative and taking calculated risks.
