Okay, since you asked.
I played multiple sports at a very high level in high school. Focused solely on baseball in college. Was successful (lead the team in hitting) until I was limited by a pretty serious medical issue. That ended any hopes of a career past college. Hard to say how that might have gone...who knows.
Probably understood the finer points of the game even better than I could physically execute them. It's been awhile, so a few things may have changed, but I still know what I'm seeing when I'm watching a game.
My career was in another field that was extremely demanding (far moreso than sports), both physically and mentally, and I reached the very pinnacle of that one. Reached the pinnacle of a couple other disciplines as well. I know the difference between good and great in general, and what it takes to get there. When I wasn't busy "doing", I taught people how to make the leap, so I get the coaching angle as well.
That's about all I'm going to reveal on an internet message board.
(I don't really care about message board cred. I just like to comment on/discuss baseball while I'm watching the game. People can think what they want and say what they want, even the stuff they'd never have the balls to say in person. I get a kick out of it, actually.)
