arlovski is a former champion who fell from grace and is making a late career comeback. he's ranked #6 in the UFC HW division, why would he fight #12? he gains nothing from that fight. he could win and drop in the rankings.
mitrione is meathead, but to say that arlovski took a beating from rumble, he must not of watched the fight. rumble dropped and nearly finished arlovski to end round 1, but after that, arlovski picked rumble apart as rumble clinched and tried to take arlovski down rounds 2 and 3.
