well as usual I disagree with Von on a boxer always winning the standup against an mma fighter, but Tank is basically a glorified toughman fighter and would be handily beaten up by Tua in a boxing ring or an octagon. The guy really has never beat anyone worth mentioning and shied away from some big fights with the likes of Ken Shamrock and others. He is a lot of fun to watch, but other than sheer punching power he brings little else to the table.
