There are some guys that can finish you early, but to me the scariest type of fighter is the guy that just gets tougher after you tag him a few times and the fight gets more gruelling. Here are some dudes that you better finish quickly because they get tougher to beat the deeper the fight goes. Tony and Khabib both fit the description, that fight is gonna be a war. Stipe and Jones too, that’s another fight that needs to happen. Who else?
