Stipe's game plan is probably going to be circling on the outside and jabbing. He's not going to be throwing his body weight forward with the punches right into DC's clinch which means his punches are not going to be knockout punches. DC's also pretty durable.
The first fight also showed DC could not take Stipe down even when Stipe was giving him the clinch. Nor will Stipe enter the clinch or waste energy trying to take DC down.
I think DC vs Stipe has a good chance of going to a decision for a HW fight.
