There really is no rigid coverage area in transition. The Lead can get help from the C and the C can get help from the Lead. The Lead might have a better angle based on the type of play or the C might have a much better look. Both officials could have a whistle, just get the call right. Once in frontcourt coverage you can go back to the rigid coverage areas. But the C position is designed to "help out" if you will. I guess you could say the Lead has the first crack at the call, but the C can make a call if the Lead misses something.
