It's probably jsut an experience thing. A player will always get better as they play more games they can work with their team better and stuff like that. Don't let it get you down it aint worth fussing about. It sounds like you aren't the biggest of team players. I say that with respect you may well be but from what i can see you maybe aren't. Not that there's a problem with it but it's alot more important in organised ball as opposed to street to ahve good link ups with your team. You might even be looking in the wrong places when it coems to your stats. You get 10 - 15 ppg which isn't too shabby but that may not be your big strong area. You could be grabbing 15 boards or zipping passes through and getting a tonne of assists. It's not all about the points in an organised game.
