I don't know. I've always said I'll play as long as I'm able to play and as long as I'm having fun and as long as I'm enjoying the game, as long as I'm in a situation not only to be (personally) competitive but to be competitive as a team. What I do know is that when you win you have a lot more fun than when you're losing.
