I don't have any concerns fighting a teammate. It's a sport. To me, it doesn't really mean anything.
It has nothing to do with swimming. That happens to be my sport. I'm trying to see how far I can go.
Togetherness is huge. I just can't see anybody getting results in team sport without being together.
Field hockey is my strongest sport, and if I lose a game, I take a long, hot bath and moan about it.
There will always be cheaters. It is human nature. It will never be 100 percent clean, in any sport.
