This is totally different than Brock - I see this going either way. JDS is no poser like Brock, man hits effing hard and is a real fighter.
Theyre both gonna want to stand. They both have knockout power in each hand.
Overeem has those big knees. I think if Overeem gets inside quick he'll be able to end it with one of his Uberknees.
Otherwise I think its a crapshoot, either one has the ability to end it with one or two good shots.
Should be an entertaining fight, its much more entertaining to watch 2 strikers fight than it is 2 wrestlers/ground guys.
