Excellent summary. I'd add a few points which may not interest anyone but me:
6a. Gregory was hired March 28, 2011. The AJC printed the
memorandum of understanding. It called for "Annual base compensation of $1,000,000, with no escalating value for at least the first two years". It also stipulated that the contract would include: "Provisions in which the ASSOCIATION agrees to review the contract with Coach Gregory within 90 days of the end of the 2012-2013 season."
6b. October 29, 2012, GT confirms that Radakovich has resigned to take the job at Clemson. Paul Griffin will serve as interim.
6c. January 16, 2013, GT announces Bobinski as the new AD, but he will not officially begin work at GT until April 1. Subsequent interviews make it clear that he is involved to some extent in GT matters during the interim.
6d. March 14, 2013. GT MBB loses to Boston College in the ACC tournament, ending their season (since there was no post-season invitation) and presumably starting the clock on the 90 day window to review the contract.
6e. April 1, 2013, Bobinski officially begins as GT AD.
6f. November 12, 2013, a one-year extension is announced for Gregory. The buyout schedule, as covered by dtm, isn't mentioned in the press release.
Without seeing the contract itself, I have no idea how the idea of fixing the salary for the first two years and then having a "review" was covered. It seems odd to me, but I'm not a lawyer and have no knowledge of coaching contracts in general. I guess I always assumed that a coach would have a defined salary, and if they out-performed this they had the leverage to get a raise. Would there have been a definitive obligation on the GTAA to take some action beyond just a review?
