If Kevin Randleman can get inside on Mirko then Tyson shouldn't have a problem. Mirko got leg kicks but he doesn't take pressure as well as people think, he likes to keep a distance and he has a good submission game, but Tyson would bullrush him from the word go and before Mirko could get a shot off Tyson would be on him, Tyson wouldn't just sprawl with no defense or form in his punches, he would and could beat Mirko. But if Tyson stayed at a distance where Mirko could pick him off then of course Crocop would win.
