I'd be surprised if Chun didn't start putting his list of candidates together this summer when it became obvious that Rolo was going to buck the Covid Vax mandate. Love him or hate him, Chun comes across as someone to me that is pretty organized and doesn't like to get caught off guard and unprepared (which is a death knell for an AD that wants to climb the ladder). As fun as it would be for fans to know all the inside games going on in the HC search, we're never going to be privy to all the facts in the process so the second guessing that is coming our way (for whatever choice is made) by the media and fan boards are pretty much going to be "guesses". Some will be very entertaining guesses, but guesses nonetheless.
As far as Dickert, I like his chances and hope he's the guy IF during the interview process he's able to talk thru and have a solid plan for most of the question areas and potential weaknesses that Biggs mentioned in posts past relating to his lack of experience as a head coach. (I've conducted a lot of interviews over the years -- it's easy for candidates to talk about their strengths. I want to hear about what they perceive their weaknesses to be and how well they address them by bringing in systems or people around them. Same applies to experienced HC's interviewing, but with Dickert never having been a HC he's going to need to acknowledge that there are pieces he's never done before but has a plan for his program to address those. By virtue of his "on-the-job" training and incumbency, he's also going to have an inherent advantage in some areas.) At the very least, this will be a very entertaining process to watch.
