This is probably a good move. He’s still probably nowhere near his overall potential as a fighter, and most of that has to be unlocked through training rather than more fights. It’s always good to have a few tune up fights to make sure you’re up to par and mentally all there, but there’s really no reason for him to keep doing it over and over. Once he has a little bit more time to perfect his striking and submissions I’m sure he’ll come back even better (which is a scary thought).
