My theory: On some plays, it's better for BU to take it; on some, it's better for PU to take it. But, you don't know which type of play you have until it's over (or at least too late to react). So, someone gets burned under one mechanic, and switches. Then, someone else gets burned under the change, and changes back.

My conclusion: Coaches "understand" that the play at third could be tough for either umpire, and they'd rather have the help on a pulled-foot or swipe tag at first. So, PU should stay home and BU should have both calls.

So much for PBUC having a "good theory". When I was in MiLB, BU took both.
