9 more wins than losses while hitting your prime has tons more upside than 6 and being 46;D You forget BJ was fighting heavies in open weight contests.. I would say BJ struggled at Welter he dosent belong there, he rules his division and will for years.
Randy fits the mold and thats why guys like Rogan have a bromance with him, but seriously 16-10 is both overrated and mediocre. Not like Holyfield who is clearly past it and rides the merit of his past greatness, he will have a gatepass and history will be more kinder for the majority of the end of his career when looked back on. Couture on the other hand has no excuses, he and his legion of gushing fanboys have removed his age as being a factor in the equation with all the Randy is superhuman Bullshit. So I think every loss is really killing his legacy, his much hyped legacy
