I'm trying to put my mind into Kelly's on this. What makes sense to me is that he had an idea that was good at one level, but upon judging the whole logistics turns into a bad fiasco.
Kelly tries {this time too hard} to systematize everything in order NOT to embarrass the players nor the University. He surmised that if we lost a home game, particularly an excessively disheartening one, the immediate emotional responses by the players could be "inappropriate" in a variety of ways to be scrutinized by the panning of national TV cameras during the alma mater.
His "solution": take the team "in" [many coaches do such things before letting media get their shots at them], and have a few words to calm them down and get them re-focussed and "presentable". So far: wise.
The trouble was that not everyone's a Spockian Logic Machine like Kelly, AND the expectations of what exactly would happen post-game [and at what PACE they'd happen] weren't in everyone's awareness [by a long shot]. The emotional chaos of game's end could NOT allow Kelly's scheme to work [no matter how appropriate for what he was trying to do], and he, for once, blew it as far as thinking the complexity all the way through. {He could have saved the plan by going to the microphone and telling the fans that the team needed to take a moment, and would the band leader please wait for them to return?}
This scenario SHOULD improve people's view of what TJ, Lou etc were doing. THEY remembered what the coach had said and were doing the team policy. It would not be their job to go against what their HC thought was best.
