I don’t think that the bodybuilders would do to good, but they are huge. Strength would play an overwhelming factor. Tyson on the other hand would likely kill someone. He is huge as well. 5’11" and 220-230 lbs. He has crushed peoples bones in their face in under a minute. And the guys he fights are huge. They are not 160 pound guys. Plus Iron Mike would not be fighting with gloves on.OUCH! And he has conditioning and a lot of rage.The key to beating a grappler is to wait on them. They wait for a move to be made and look for an opening.
