JugglingReferee wroteI believe that the defender had LGP. But this is easily a no-call.
I'd like to know if the dunker said anything to the defender. If so, and it was untoward, I'd T him up.
Why would he have to say anything? He just threw it on the kid's head and then he stands over him. He "said" all he needed to say with the stare.
If that's not called as a taunt we're asking for it to happen again...which means we end up writing post-game reports that include the line "...and then the fight started."
