The fans and alumni might have been disappointed given the success last year, but he was not close to being fired.
Adams went to the Sweet 16 and was given an extension after his first season. You don't fire the coach for winning five games in conference in his second season (first with the extension and the full buyout) unless he gives you an out, which Adams did.
I don't care for the guy or Tech, but he was coming back for the second season of his extension next year. The AD is like a GM, and you don't cut first round draft picks after a year absent extracurricular stuff because it reflects poorly on you.
