I think Coach is here to stay unless one of these teams that could conceivably have an opening comes calling, whether this year or five years from now. These are based on a combination of factors including location, pedigree, and size of market. Anywhere else feels like a lateral move with less job security.
ACC: Carolina, Miami, Cuse (hate to say, could make sense for them though), Notre Dame
SEC: Mizzou
B1G: MSU (hate to say again, but this is my gut for 2020-21 after Izzo retires, which would be awesome for Nate), Michigan, Wisconsin, Iowa, OSU, Indiana
BIG12: Texas, Oklahoma, Baylor
Big East: Nothing comes to mind
I'm staying positive about the situation, but still if I were an AD at one of these schools, Coach would be the #1 target on my radar. He's got it all, media savvy, intensity, face of the program, young enough to build for decades, experience with kids from tough backgrounds, and maybe the most underappreciated trait, a feel for numbers, patterns, and analytics.
This is just for the fun (and therapy) of speculation. I want Coach to stay as much as anyone and thankfully what we post here will have no influence on what comes to be.
