Seriously though he is taking a big gamble. He is throwing the dice with his future career in a big way. If in his first fight he gets knocked spark out, he's got a glass jaw and there are lots of close ups of his sweaty carcass of a body, bald pea head mouth open, unconscious on the canvass. Bang! There goes playing the big, scary tough guy in films, etc....the perception would be shattered.
Especially if it's a Dad bod that wrecks him..
