There is no more difficult test for an athlete than wrestling. If the person across the mat is better than you, there is no place to hide. You are going to take a beating and then have to return to the wrestling room the next day, a harsh place with walls permanently drenched in the odor of sweat, to work for three more hours to improve your skills.
As an outsider, I've always looked at wrestling as the sport where there's no fun. OK, there are a couple of minutes to celebrate after you have pinned or gained a decision over an opponent, but then it's back to the next sweaty, nasty challenge.
There's always someone around the corner tougher than you, maybe trying to take your spot in the lineup for the next match, or maybe the guy at your weight coming to town for Penn State, or Iowa, or Oklahoma State.
Even Dan Gable ran into that tougher guy one night.
Wrestling is a sport for hard men and, frequently, hardheaded men, and J Robinson is 100 percent qualified in both categories.
Robinson had spent 30 years coaching and controlling the University of Minnesota wrestling program. On Wednesday, that tenure came to an end when he was terminated as coach by new athletic director Mark Coyle.
We could go through the details of the non-prescribed drugs that permeated the team, but in the end, Robinson has been brought down for the reason most of us figured would be:
Hardheadedness.
