Shane Carwin, who at one time held the UFC interim heavyweight championship, announced earlier this week he is retiring from MMA. Carwin was a dangerous and exciting HW. Although his base was wrestling, He was never afraid to stand and trade with anyone. None of his 12 wins ever went to decision — he finished, by either KO, TKO, or submission. As far as I know, Carwin remains a full-time engineer, so he’s already got a decent job. Hopefully, he’ll stay in touch in the world of MMA in some capacity too, whether it be broadcasting or coaching, etc.
