How to handle?

[Ray_from_Mi]

Had this happen last week and would like some healthy feedback on it. This won't be long, just looking for a 1st impression. I'm C, the point guard in his front court starting to drive down the center of the paint. We split 60-40 between T and C out above the paint so we don't get caught up in both watching in our primary. Okay, this kid starts his dribble/drive and goes into a 'rainbow' layup starting on the outsid of the free throw line. When he finally is coming down and contacts the defense, he's about 3-4 ft. from the front of the rim. Question here is this, should this be the trail's call because it started from his area? or should this be the C's call because of where the foul,(if there was to be one)took place. Alot of us are getting wrapped up in the adage that, 'the play came from my primary'. Well, thats true in all the fouls called, they all come from someone's primary. Comments?
