I guess it's nothing more than a mass publicity stunt from a company that's on its way out.
Chances are they'll make a huge fuss out of Kimbo and Shamrock fighting again to try and generate some cash.
Although if by any measure that happened to be genuine (the whole premise and actual replacement match) then Kimbo is the biggest waste of space ever and would have been slaughtered by Shamrock who is way past it and overrated to begin with and that's bad enough.
The first kick connected (if you can call it a kick) but the follow up kick missed and that so called overhand right (idiots) missed and he didn't look off balance at all to warrant a sudden fall. Watch it in slow motion it really does look like a setup found within the WWE.
