Frontcourt Corner Coverage

[APG]

This happened in a game from the same Nike tournament BNR referenced in his thread:

Team A is in their frontcourt set. Double team pressure by the defense on the wing forces A1 to pass it to A2 in the corner.

I'm the lead out wide near A2. A2 puts up a three...B2, while A2 is still in the air, hits A2 on the arm, and the contact is more than incidental/marginal. I wait half a beat for the trail's whistle...then come in with the foul.

I had one college official (NCAA-M), who was one of the partners for the game, says that's a call you have to get...even from the lead. Also had some feedback, from some other officials, that asked, if I'm looking out there, who's looking at the post/rebound action.

What say you? What are your thoughts on the lead coming in on a foul on these types of plays?

Obviously, the play above is for NFHS/NCAA-M mechanics.
