Clough hired Braine because of their time together at VT (and their wives' time together at VT). It is true that Clough was not a friend of the GTAA. He did a lot for Tech academically, but he was no friend of the GTAA. However, since Braine was Clough's guy, was Braine a co-conspirator?
Braine was horrible. Homer left the GTAA in great financial shape. Braine spent the money and didn't do fund raising, which is job 1 for an AD. Defending Braine on any level is absurd.
O'Leary could rankle people alright, but he was very strict about his players attending class and performing academically. People blame O'Leary for flunkgate, but they are confused. It happened under Gailey, who didn't understand GT academics and treated them like NFL players who only needed to show up for practice. Since they were O'Leary recruits, which is the way the NCAA looks at things, O'Leary's reputation took the hit, but flunkgate would not have happened under O'Leary.
I give some credit to Gailey though. He learned and improved at managing a BCS program, and he became a good at recruiting--if only he had put aside his ego and hired a good OC. Then we fired him to hire another mediocre coach--at twice the money. Mistake after mistake by the GT adminstration (not just the AA) from Braine to Bigfoot.
