If thats what he wants...he'll need to coach a Div III college team...
The vast majority of college players including Div 1 of the 10or 11,000 that come to play each less something like 200 will see an NFL paycheck.
Black Irish's quote is a paraphrase from Lou Holtz's termination pressed from the NY Jets. Holtz noted he knew how to motivate college kids but didn't have a clue as to how to motivate NFL millionaires. (Broadway Joe closed more bars that season than he closed out games.)
Keep in mind that was based on his being a head coach at William & Mary and NC State. How many of those players ever sniffed an NFL paycheck?
At Arkansas he took a 16 point underdog in a Orange bowl game against Switzer's Sooners. Holtz All-American guard was lost in practice. Then a day or two before the bowl game he suspended his two leading RB's and his leading WR for team rules violations. (The violation later was learned to involve a naked woman in a player's room.) Talk about motivating college athletes, behind a patched up Oline the 3rd string RB ran over the Sooners for more than 200 yards.
Years later Holtz suspended Watters, et al for showing up late for team meetings before a game with USC in LA. Holtz sent his suspended players home by plane before the game started. The Irish won without the stars just as the Hogs had done.
Holtz used to give his players written tests on the history of rivalry opponents.
He took his players to a hotel the night before games and them them visualize making great runs, touchdown stopping tackles, ... positive reinforcement.
He stamped his W.I.N. Philosophy on HIS TEAM. W.I.N. ... What's Important Now.
Try sending NFL players home, written test on rivals, W.I.N. ...
"Yo coach, I'll get back to you on that play. My agent is setting up a multi-party call with our lawyers and ny union rep about that play violating my contract. We'll make it quick as there's a crew standing by to film a commercial and my business agent's waiting to discuss the franchising deal."
