I don't believe Frank's health is bad, or getting worse. He looks and sounds to me like he is improving. When Frank sits down with Tanner after the season and talks things over, I think Tanner is going to realize that this season is not reason enough to fire Frank. Frank isn't going to resign, so if he leaves he will have to be fired. I don't think Tanner is going to do that and pay Frank $6.5 million not to coach USC. I think Tanner is going to give Frank another year that will hopefully be without Covid and see what happens.Yeah, not a good look for us if we can Frank. Unless Frank has serious enough health issues that he is ready to call it quits - and says so.
Outside of his ties to Frank, Anthony Grant had limited success at Alabama, so he would not be at the top of my list. We already tried that in football - hiring someone that failed at another SEC school.
Boynton would be a good pick, but we would not be a step up and I am not sure how strong his ties are to his alma mater. But no need to dwell on this now - we still have a coach.
There are always going to be coaches available that will be interested in the USC job. It isn't like we have to move quickly to get a certain coach or he will be gone somewhere else and we'll never get him. Such a coach probably does not exist anyway. Hopefully, Frank will be the coach next season and it will be a good one.
