I believe the clinics are an appropriate place for umps to ask what if questions. They are doubts those umps have and to get them answered is all positive. Those that know the answer have to "put up with" the learners.
. If everyone got a casebook and read the ASA clarifications and plays, then the number of what ifs would be limited to advanced questions and concepts.
On the what happens if a runner runs into the ump or the ump runs into the runner, the UIC had to help out the presenter in providing the correct ruling. It was not Mike.
As for a runner running into the ump and then getting tagged out, the out stands. It is in the casebook somewhere. That had to be clarified.
