Kimbo is a complete joke and any comparison to Mike Tyson is as well.
You see this big Irish lug a young Mike Tyson is fighting? 9 wins 18 losses. But big and tough with decent skills (much like that Boston cop), it took Mike 4 rounds to dispose of him.
Kimbo wouldn't stand a chance with this type of fighter (big, decent skill and jab). He would literally be gassed and wanting to throw in the towel like a bitch after about 3 rounds.
Slice is all hype and all about money, it wouldn't shock me in the least if we see him involved in a few rigged fights at some point in the near future.
