have u watched Mayhem fight? 2 shitty fights in the octagon shouldnt leave u thinking hes a shitty fighter, maybe he just has shitty nerves.
i blame his "gassing" on an adrenaline dump more than anything. BUT, he honestly isnt that great of a fighter. he's by no means shitty, but the words "average" & "mediocre" come to mind. or perhaps just untested (i know, i know..he's fought gsp & shields. & lost).
looking at his last 10 fights, his most notable win was over Tim Kennedy (14-3)
4 years ago. here are the records of the other fighters he held victories over within that 10 fight period--- 9-6,
4-11, 7-5, 12-10, & 26-16 (sakuraba is in his forties).
the quality of opponents he has defeated has been pretty weak IMO. i personally dont believe he'll have much success in the UFC. they'll probably set him up against someone with shitty TDD in his next fight to get him a win... but he's still a faggot.
