im 300lb or so, very strong, relatively fit and a dan grade at judo with some mma/kickboxing/boxing training behind me...if , and this is always the big intangible, IF i can avoid the almost innevitable clip on the chin and get my hands on him, id be confident of beating him.....but if he stunned me or caught me i guess, realistically, im gonna have a short kip...
He would beat me, to heavy. I would just be surviving unless i can slink round and get his back...my only chance.
