As I stated in another post, Stansbury's last five or six years would rank as the fourth best five or six year period in the program's entire history, with three NIT's and two NCAA's in that time frame. So I'm not sure what you mean by "stopped going to tournaments."
Kennedy was on the hot seat because he'd been there a long time and hadn't accomplished much. He signed Marshall Henderson in order to get some talent on the team, and it worked. He kept his job and they made the tournament for the first time. If Kennedy had not have brought in Henderson, he would not be the coach right now.
I agree that the administration fired Stansbury over the issues you raised. And I agree that it gave them the cover they needed. They didn't like him. Most fans who wanted Stansbury gone, however, wanted him gone because they expected him to go farther in the tournaments. They expected us to be in the NCAA's more often.
The backwards looking fury over some of this stuff from fans is, in my opinion, an attempt to rationalize, perhaps subconsiously, what has since happened since. 40% of all college basketball players transfer. Lots of teams have trouble with social media. Players get in trouble and are suspended. This happens everywhere and its hyperbole to suggest that our program was "imploding" or a "dumpster fire." In many ways, Stansbury disciplined his players more for these things than other coaches do. Players were booted from the team and suspended for key games.
But we'd somehow gotten our internal fan view of the program into a completely unrealistic situation. Our fan base believed that our natural place in the college basketball world was actually higher than it was when it was actually lower. Whereas most successful coaches are defended by the fan base, ours perceived him worse than the rest of the world did.
Taking the risk on Sidney probably cost him his job. That was the one situation where Stansbury definitely did not deal with the situation appropriately. And like I said, it gave the administration cover to fire him. But that was a calculated risk that failed, just like Dontae Jones was a calculated risk that worked. But even when everything went wrong, we were still a decent team.
