Regardless of whether or not UConn goes 4-8, I think the premise here is that they do. And the question is, if they do, what then transpires? Personally I think the odds of a coaching change probably rise a bit above 50%.
But coaching changes are very disruptive (and expensive). New playbook, new philosophies, and coaches seem to adopt whatever has worked for them in the past rather than going through an analytical period evaluating personnel, hiring a staff adept at coaching the new philosophies, yadda yadda yadda. There is no time for any of that. They gotta hire a new staff absolutely ASAP, prevent current players and recruits from defecting, get out on the recruiting trail, put together a new playbook, etc. All in a very few weeks. So they go with what they know and work with their professional and friends network to find staff and hire quickly. Then there is the issue of returning players learning the new playbook and the techniques required to execute it. Add that to the new regime doing game coaching for the long term rather than the short term and you have a setback of a year of two at least.
If I had to guess I would guess that Bennedict gives Diaco one more year under this scenario even though my brain says he would probably act immediately.
