I'm not a fan of the possession arrow. Why can't they just do jump ball?
I remember reading somewhere that they instituted it because there was a tendancy of size disadvantages between teams. It has its good and bads. I hate that it sometimes doesn't reward great defense, but on the other hand, it allows some great strategies at the end of games.
I would like to see it go though.
I also read that college refs had a hard time throwing the ball straight up. That just sounds ridiculous though.
I would also very much like to see defense rewarded for great play - in certain situations i'd like to see tie-ups just go to the defensive players team period
i also think the NBA should institute the 1 and 1
