There has never been a LW in boxing or LW in mma that went from LW to HW and dominated. Never happened and never could. Holyfield was the lone exception, though being a cruiserweight
I sure the hell hope not, there’s a 51 lbs difference from LW to HW.
Cruiserweight in boxing is so close to heavyweight it’s not even worth discussing, kinda like acting like JJ can’t fight and be competitive at heavyweight...
