I would take Conor to the desert. No mobile phones, no laptop computers, no food. He eats what he catches under the moonlight. Lizards, mice, dung beetles, etc. He gets water, but only after earning it. How does Conor earn water? By not getting taken down. No TDD...no water.
Conor McGregor needs to re-learn how to fight as if his very life depends on it. He needs to be stripped of everything. He needs to be broken and rebuilt, strengthened by the scabs and callouses that cover the spots rubbed raw through flagellation.
After all of this, will Conor beat Khabib? No, that's a ridiculous notion...but he will be at peace with it.
