I played a lot of sports, but I never really felt like a team player in any of them. Not because of a lack of effort but because everybody ignored me for some reason. My favorite example is this one time I was playing basketball. It was a scenario like this...
______B
_____________P
X____________X
______M
______O
B=teammate with basketball
P=person who he passed the ball to
M=me
X=other team
O=the basket
I was wide open and the basket was right behind me. The ball could have been passed to me no problem. I wasn't covered. Instead, P got the ball and nothing good happened.
That was far from the only time something like that happened. That happened all the time. I played for some four or five years and only ever made four points. Not because of the lack of trying. It was the lack of having the ball!
I got into this floor hockey league in grades 5-8, and that was a really good experience. It was on foot in the gym, but it was awesome. Lots of good team play. Lots of good passing. I got a number of goals. In gym class we would play shortened versions of that league, and there was one day I got three goals in one day. It was the closest thing I got to being a big sports star in the school. But I didn't care about that so much. I just wanted to play hockey. The best part was right before that hat trick, everybody on the other team started playing dirty, and I beat them all clean. I didn't have any fancy moves. I wasn't that skilled. I just had the presence of mind to play well.
As a completely unofficial thing, back in elementary school I was really good at wall ball. For those who don't know, the general rules we played by were a bunch of guys, one wall, a few balls, and three strikes. If you drop the ball on its way towards you from the wall, you have to run to the wall and touch it before somebody else can pick up the ball you dropped and hit the wall with the ball first. If you were too slow, you got a strike. Three strikes, and you were out. It was just a bunch of guys goofing off, but it was real competitive, too. In fact, at the end of 4th grade I organized the 1996 wall ball championship. That was a blast.
Starting the next year in middle school, it stopped being fun. The asshole bug infected practically everybody. People would "peg" other people. That was when you would throw the ball at somebody instead of at the wall. Some douchebag had the nerve to turn around, peg me at point blank range in the face, and then said it was an accident. He did a 180 and called it an accident.

that. The final straw for me, though, was when I had my arm back ready to throw, and somebody held my arm back as I was moving my arm forward. I never hurt that much before in my life. I thought my muscles were torn from the bone. I never played wall ball ever again.
