The Bo You Don't Know (2015)

That would be football coach Robert "Bo" Rein, whose pedigree could be traced to stints under Woody Hayes, Lou Holtz, and Frank Broyles. A former baseball and football standout at Ohio State, Rein was building a reputation as an innovator who inspired those around him. He became the youngest head coach in major college football when he took over at NC State at the age of 30.

Unfortunately the movie The Bo You Don't Know is not yet available on HBO Max.
