It was never in my spirit, in my heart, that God wouldn’t allow me to coach again,” Coach Prime said, via AP. “I just didn’t want to be running down to the hospital once a week when I have all of this on my plate. I don’t want that. I was like, ‘OK, can they bring one of those machines and put them in the office?’”Sanders will look to help the Buffaloes compete for a Big 12 championship.
