Just had this happen saturday in GV. Girl at line, late in game. Dribbles three times. Looks at basket. Goes to dribble again, hits her foot and rolls away.
I was trail (2man game). I looked at my partner and gave a quick shrug like, I *think* that's a violation but I'm not sure.
He wasn't sure either, but he handled it with style at least. He retrieved the ball. Made a point of looking it over as if there might be a defect with it. People chuckled as he bounced it back to her.
Fortunately for us in this case the score wasn't close/the Team B coach didn't complain. And after the game I said, Damn, I need to get clear on that in case it ever happens again.
(Thanks, Forum search feature!)
