IMHO One thing I haven't heard anyone mention is why does the Umpire go to the bench to explain the call!? I don't see that he is in any position to provide any insight on the "judgement" used. Guess when in doubt, send your largest crew member over to subliminally intiminate the coach.
It's also intersting the official who ran in 12 steps to mark the ball on the 2 blew off Coach Tressel inquiry as to what went on. You would think he would know waht happened.
