I wouldn't say say "fraud." He's still a championship level fighter. He has some good legit wins. Kambosos, Regis, Loma so on. He's a talented & dedicated kid.
The email belt knock is true. So that was a bit questionable from the start.
And he's clearly not the P4P next Mayweather protégé that many billed him as.
His chin & legs aren't as great as they should be. He's too big for 140 but lacks the power to leave.
So yes, he's a very flawed & potentially overhyped champion. But he has every right to blame the blatant weight cheat or to think things might change if he wasn't fighting a legit welterweight next time.
Be fair. At least the kid didn't quit on us. They made it an entertaining fight for us. It was trending towards unwatchable.
