I joke about this happening a lot, but it actually makes sense in a lot of ways. Urban has coached at some of the nation’s premier schools, won multiple national championships, and has had unprecendented amounts of success. If he came back to Utah and was able to get to the CFP, or win a title, he would be cemented as the greatest college football coach of all time. It’s one thing to win a title somewhere with top 10 recruiting classes, it’s a whole other thing to win a title at a place like Utah (a good, respectable program but doesn’t consistently land elite athletes).
He is revered at Utah, and could coach here with with relatively little stress. The expectations at Utah are much lower than they are at places like tOSU, Florida, and USC. If his health problems are in any way exacerbated by stress, but wants to coach again, it makes sense he would look at a place like Utah where it is a less stressful coaching environment.
It’s a far-fetched dream at this point, but stranger things have happened.
