I don't quite understand how he can come from a family of boxing gypsies and be so bad at it. His brother is categorically one of the most skilled on the planet and yet he can't even box to a pro level? That's an extremely low bar relative to the training and family he's coming from.
Baby Benn, baby Eubank, baby Hatton all at least made the bar. His own family make it the most damning, though and I don't get how he can come from that stock and literally be a YouTube boxer standard.
These fights are blessings for him to be fair: he's making far more money than he ever would toughing it as a rank climber, and for a literal fraction of the damage and health concerns. He should be offering KSI a rematch and hamming the robbed angle to the utmost to fire up KSI's following and see if they'll be stupid enough to pay for the privilege of watching them go at it again under a justice/revenge arc. It's his only realistic hope of making anything like this amount of money again in boxing; with that performance, he's a reality star putting on gloves, just like his opponents; the pro angle has gone for him now.
I don't think this stuff tarnishes boxing. The only damage done is to Tommy's own career and reputation, and it's him who risks being jettisoned and exiled. These freakshow bouts were undertaken by Ali himself, with zero harm to his standing. It's the boxers with everything to lose, should they be defeated. Boxing itself remains untarnished: you either show that you represent what being a superior pugilist is, or you're no longer able to call yourself a pro without being seen as a joke, should you be troubled under the Queensbury rules that should leave the non-pro floundering.
