I'm not being confrontational but am curious where you get all of what you assert. My statement is from two sources both alums of whom I've known for over 50 years (I actually started elementary school with both of them in about 1962... wow, that's actually 60 years) and who both have very strong connections to the school and the AA.
I do have to say that it is all speculative. Some of it is more certain than others.
The $4 million donation: CPJ said on a radio show in either 2014 or 2015 that they had done preliminary arch/engineering for a new locker room. That CPJ and a donor, willing to pay the $4 million price tag, had gone to the AD to present the idea, but it was rejected. Not long after TStan came to GT, it was announced that an anonymous donor was paying for a new football locker room, which opened in 2018 I think. I was not involved, and did not personally speak to anyone involved. However, I think the coincidences are too large for it to not be the same donor. I think the coincidences are too large for it to not be the case that MBob turned down a $4 million donation that would have helped the football program, and very quickly after starting the job, TStan accepted it.
As to the sabotage, that is indeed more speculative. It is a combination of things such as: Locker room as described above. MBob's radio comments during 2014 which insinuated he was planning to fire CPJ at the end of the year. Rumors about a few large donors urging Mbob to fire CPJ. Begging, and sometimes publicly begging by CPJ for resources for the football program. (recruiting personnel, operations and travel staff, etc) Decline of spending on the football program during those years, even as athletic association revenue increased and the percentage of revenue spent on football declined compared to other ACC programs.
I don't have any inside information and did not personally witness anything directly incriminating by MBob. However, between DRad and TStan, the GT football program became the second lowest funded football program in the ACC. I haven't looked at percentages, but I wouldn't be surprised if it was the lowest funded as a percentage of athletic association revenue. It didn't take long after MBob left to get funding for a better plane for the team to travel to Ireland. It appears that anything that CPJ asked for was denied. It also appears that funding wasn't the reason for denial. The locker room money was already available. The money for a better plane to travel in was found within a month. That leads me to believe that the reason for the denials was that MBob didn't want to provide CPJ of any requests.
