Well I think; you shouldn't copy and paste from this source ever again.
I also think I don't what the heck really happened?
With his "understanding and knowledge" of the appeal rules", he should know that all runners can touch a base at the same time; long as they all fit, nobody passes anybody, and nobody gets tagged.
I also think BR doesn't play HS(FED) rules so, this indicates to me this BR All-Star team went and played in a non BR sanctioned tourny. Ran into some non certified in anything Umps.
Initial call on the appeal of R3 would be the PU's call an appeal of what ever they thought R1 did or didn't do would be BU's call, so if PU was making all these calls and doing the splaining, I think I just verified my comments about the quality of the Umpire crew.
