Mayhem is a cool dude,a tough dude as well,scarless.Hes an "elastic" man,and so and so....
But to be honest,hes not what we can call;A top-fighter!Entertainer;yes but he may have long limbs(which are a great assets for him)but hes not strong enough to compete with other top 170.So when he go up to 185,like @SuicideKing said;"...get thrown around like a puppet."And its been like this since he got into the bigger "league".The guy cant wrestle!And its the truth.
I remember seeing him fight(long time ago)guys way below his talent level as far of technics,but they were so much stronger than him,that they wrestled him to the floor all the time!He got up,and he went down as fast!!!
Strength and wrestling abilities!
Hes the kind of guy I'd love to have as a friend,and/or as a MMA coach.
Best of luck to him.
Also,I'd love to see him choke Nick Diaz to...sleep!Or to KTFO of him!
