I've often wondered how well an extremely gifted natural athlete would play the first time he picked up a tennis racquet. For instance someone like Danny Ainge - I'm assuming he's a natural as he played both pro baseball and pro basketball. I could imagine it going either way - 1.0 or 5.0 the first day. My own knowledge here is limited, well, non-existent. I seem to remember reading years ago that Jimmy Brown played intermediate tennis his first day. That's all I remember. I'd be curious to hear from pros, anybody at all, who knows something about this.
