I had this twice in Girls JV game on Wed night.
First Time: [Blue Team on Offense]
A1 passed ball to A2, B1 tipped ball, A2 while in front court, deflected it into BC, A2 went back into BC and retrieved ball, I was trail, saw the whole play, tweet, BC Violation, gave ball to B at sideline nearest to where A2 grabbed ball. Coach screamed "it was tipped, it was tipped", I told Coach I saw the tip.
Second Time: [White Team on Offense]
A1 passed ball to A2, B1 tipped ball into backcourt, A2 waited for ball to bounce in BC before picking it up. I was trail, saw the whole play, no whistle, and we played on. Coached screamed "Hey that's over and back, how was that different? At the next TO I talked to Coach and told him easiest way to tell violation/no violation is to look at "last touch first touch" even if it's tipped by a defender in the FC. If offense is last to touch in FC and first to touch in BC, you got a violation, If defense is last to touch in FC, then play on.
He had the "deer in headlights" look like what in blazes are you talking about?
I guess I'll have to 'splain it a little slower next time.
