I had a grade 2 ankle sprain in high school that I got during basketball season; anybody who's played has probably done that open court drill 3 on 2 that transitions to 2 on 1 when you come back the other way. Anyway I was part of the final "2" and I'm a center, so I didn't really dribble much if I could help it. I grab the board and pass out to my teammate, who speeds up the left side of the court, and then I go busting up the right. The one defender is in the middle of the lane, and my guy bouncepasses me the ball in stride for me to go up for a layup, and when I do the moron defender steps directly on my shin, causing my foot to turn perpendicular to my leg at a 90 degree angle and giving me the sprain.
Anyway, there was a tourney a few weeks later and our team only had 7 guys, counting me; and in my infinite 16 year old wisdom the coach has me play anyway. I'm basically good for nothing but standing there at this point, but my man is at the top of the key with the ball on the left wing, and I read that the dude is going to try and pass up to my guy. Somehow I thought it would be a good idea to jump the lane and steal the ball, which miraculously I managed; and even more ridiculous was I beat my man down the floor with a 1 step head start (on a busted ankle with no dribbling skill in the first place). Anyway the guy was coming up behind me as I got closer to the rim, and somehow forgot my ankle was fucked up. I tried to plant all my weight on it and jump and completely crumbled, throwing the ball straight up and rolling around on the ground like I got shot and doubling up the damage from the original sprain and leaving me with an ankle that cracks pretty much whenever it moves and a tendon that does nothing
