[so cal lurker]

I would love to--but don't have one. I'm not a basketball ref--I would hope I would know this rule backwards and forwards if I was!

EDIT: thanks Billymac!

EDIT 2: I'm guessing that, in the opinion of the referee (yeah, I know that is soccer lingo, but I'm a soccer ref...), he had possession before he was on his back, so called him for rolling over rather than sitting up. From the comfort of the stands, I didn't think he had possession till he was on the back, and thought the call was for sitting up, which I thought was wrong. Of course, my opinion from the stands doesn't matter. . . I just like understanding the rules as much as I can.
