This is sad for Ray but I guess he has bills to pay...If Mercer just trains enough to get some wind it should be an easy nights work for him...after watching kimbo it's pretty obvious why he is taking the mma route, he beats up bums, drunks and kooks pretty well but a pro heavyweight he ain't! Ray may be a long way from a top level heavy but he should have remembered enough to starch a novice like Kimbo...

punching power - Mercer
boxing skill - Mercer
Stamina - Mercer
Speed - Mercer
Age - Kimbo

Sorry fella's unless Mercer just rolls over I don't see Kimbo leaving the octogon vertical.....
