re: 12th Final Four appearance for Coach K.

It's unlikely. People forget how accomplished Coach K was at a young age. He had seven final four appearances by age 47. That's the type of pace a coach needs to set to make 12+ final four appearances because that rate's bound to decrease as a coach gets older. The only coach who would have had a shot is Brad Stevens if he had stayed at college and moved on to a blue blood program. However, he's probably going to be with the Celtics for quite a while so I don't see Coach K's record being in jeopardy anytime soon.
