There’s no “singular guy” that can come in and replace Cal and be an ostensibly better or even similar fit.
Personally, I don’t want to go after one of the “big name” coaches once Cal leaves. I’d like to go get a younger (mid 30s to very early 40s) coach from a mid-major level that can run some really modern, creative offensive and defensive stuff.
Let Cal take in a GM role where he can help in recruiting and Basketball Operations stuff to ensure the biggest recruits still want to come to Kentucky. Because as much as many of y’all like to bash Cal, I have no doubts that his players (perhaps outside of 1 or 2 over his entire time at Kentucky) want to play for him and trust him to do what’s best for them.
For my “dream list” of candidates that fit this category it would be:
1) Drew Valentine (25 yo, Loyola HC)
2) Brian Michaelson (41 yo, Gonzaga assistant and lead recruiter)
3) Richie Riley (40 yo, South Alabama HC and EKU grad)
