This is an interesting question. The two people who come to mind for me, I don't necessarily admire them, but rather some things about them.
The first one is a man from my home town called "Bluey" (That's not his name, but we'll assume it is.) I grew up watching him play football for our town's club, and he was amazing. He truly had white line fever. Off the field he was the lovliest guy, and married to a beautifully wonderful person, who was my favourite teacher. But when he played footy, he turned into an animal. He was so fast, and quick, no-one could catch him, and he took the game on, and went for high risk stuff. Whenever he got the ball, or got near the ball, you knew something exciting was going to happen. All the crowd would cheer for him, and the opposition teams hated him with a passion. He was a demonic beast. I tried very hard to emulate that into my sports, because I admired that type of play. He and I are the sort of player who adds the random element to the team, who you are not sure if you want on your team, but you sure as hell know that you don't want them on the other team!
