Plenty of posters, not necessarily you, but they know who they are, have claimed that if we fire KO, we'll never get better than a D-list coach who will confine the program to perpetual mediocrity.
I'd hardly consider it early for an elite program to jettison a coach who will have (in the scenario where we have a bad 2018 on the court and on the recruiting trail) zero conference regular season titles and one NCAA tournament win in 4 years, major deficiencies in player development, recruiting, and retention, and a general inability to maintain a program.
