I don't think the comparison is fair. I have trained and coached in MMA for 20 years. The responsibility of a coach goes way beyond the 15 (or 25 minutes) in the cage. It is their responsibility to train, coach, mentor a fighter for a successful CAREER, not for a single fight.
1/2 way through the 3rd round it was clear as day that Calvin could not win the fight. He was badly injured and fatigured. It's not football where a hail mary is the same in the 1st quarter as it is in the 4th quarter. Calvin could have landed the hardest strike he could muster and it wouldn't have been enough. The fight was over. At that point, Calvin was just taking damage that could have irreperable effects for not only the rest of his career, but his life.
You know I love you. A disagreement will not change that.
That said, no. Responsibility falls to the individual. Always.
My wife loves me more than any coach ever could. She could tell me to stop doing what I do. I won't. Not until I'm done.
Surely you can understand that.
I understand your argument to a point. Fighters chose the profession. Calvin would never quit on himself, even if that means dealing with the potential consequences that could and may effect him for the rest of his life, not just put him in an early grave.
The issue is that a decision made in the heat of the moment is not necessarily one someone would make of sound mind, and as a coach you have to take into consideration whether or not that athlete would actually choose those consequences knowing they were for nothing. Calvin likely believed he could still win, so he was willing to keep fighting regardless of the consquence. He was completey unaware that he could not win that fight, and if he were, then maybe would make the decision himself.
Would you choose to continue making knives and take those same risks if for example your knives just went in the trash when you were done with them? They never serve a purpose, are never sold, are not a way to support your family, etc.
