There have been other coaches who challenged the traditional grind-it-out approach but they are rare. John Gagliardi from DIII St. John's University in Minnesota comes to mind. He is the winningest college football coach of all time 489-138-11. An interesting book on him: The Sweet Season by Austin Murphy.Wow, that's depressing to watch (only saw part 1 so far). It's hard to imagine any wrestlers coming up through the Gable/Brands system achieving their maximum potential in the sport. And any of those wrestlers who go on to be coaches are likely to perpetuate the errors at other programs unless they have some huge paradigm shift after leaving Iowa.
Cael revolutionized coaching the way Dick Fosbury revolutionized the high jump. It's like Brands and the other Gable disciples coaching now are stuck doing the antiquated pre-Fosbury high jump. I guess that's good news for Cael. He's likely to not have much real competition until some of his own pupils become head coaches at other D1 schools.
No question though that Cael is special (he would deny that).
