SAump wroteIf BU and PU are both on the foul line, then both are the same distance away from 2B. Okay, so both are identical clones and "almost" the same distance away from a place near 2B.
So what? Distance is not the deciding factor.
SAump wroteThe overthrow is toward the PU. Who should follow the ball into the fence and the carrom towards the backstop behind the plate?
BU, since he's looking in that direction anyway.
SAump wroteWho is already there to see a ball go dead? The PU would also have a hard time running in the opposite direction from a ball thrown in his direction.
BU has the same problem in your situation. Either way, if the ball caroms towards the backstop, the umpire covering second is going to have, at best, a peripheral look at the ball.
SAump wroteEven if a player collides with the BU, PU taking runner to 2B has "covered BU's ask" written all over it.
Again, so what? Once the throw is botched or the collision occurs, everyone knows that standard coverage might be out the window.
SAump wroteThe BU must be standing too close to the action and not correctly reading a bad throw. If BU continues to mess the coverage, mess the bangor, and mess the coach's explanation
You're acting on a faulty premise that BU made a mistake.
SAump wrotethen only in private consultation would the PU provide a view of the play.
So, you advocate PU giving information from a lesser position in a more haphazard way.
