Time to start from scratch.
This is what pretty much any other program would do at this point. Just recognize that the current leadership has failed, and start over. Even if that means taking a few steps back (e.g. losing some talented players/committed recruits who bolt because the coach who recruited them is leaving). This happens all the time in pretty much every other program in the country. It really is not a big deal, it is a perfectly normal part of the life of just about any college basketball program at some point in time.
But our unique Thompson-based program is not remotely normal.
