Beeware,
Please be a bit less fatalistic about this coaching staff. O'leary had issues with QB's leaving. (Crenshaw) I agree that BOB is a bit put out with staff issues...I don't agree that a new coach fires the previous recruiting coordinator. Still, if you went to Tech, there comes a poing where you don't think you're cut out for it. You either stay/go. I believe that's where Hall got to this week.
Your analysis suggests that since Hewitt didn't keep any of Cremins' assistants, Halston Lane's leaving denotes a program in turmoil.
CG has huge question marks, but none bigger than the program has itself. I do not think O'leary could have taken GT to MNC contention. I don't know if CG can do that. But I'd rather not know, than to think not.
As an aside GT hadn't won the "big game" under Oleary. Until 91-92, Dook couldn't win the "final four" under Coach K. Now Dook wins with regularity because K became a much better motivator and less of a yell/scream coach.
I don't think O'leary would ever make that change.
I'm not trying to berate you as it seems others do but there are other lines you might be able to tow.
