If the call gets redirected to the PU, as it should, the coach is probably going to want the BU to give his opinion should the PU not give the ruling he wants. You can take that to the bank, especially at the lower levels of play.

At lower levels the coach will go fishing for an umpire who agrees with him. At higher levels the coach knows who has this call.
