Nah. Well, first off he only missed twice - won one, lost the other. So you're wrong on this here. But I'm just saying, all the PED shenanigans, weight stuff, gifted title shots - weaselly stuff seems to work short term but how many guys you can name who got away with it long term?
He can say "Yay! I rigged the weight! I beat Luke!", but here we are in 2021. Luke actually became UFC champ (which you can never take away from him, he even holds a win over the champ who beat him - it's not like we don't know he can beat Bisping), he is 3-3 in his last 6 and still fighting in the top organization. Meanwhile, Romero is 1-5 and in Bellator.
So, I think these things kind of even themselves out, eventually. Maybe not mathematically and proportionally, but anyone who wants to weasel around is kind of setting themselves up anyway. So there's no point in micromanaging, just let them cheat, if they want to.
