Looks like both guys were pretty worn out from all the action earlier in the game. Definitely an edge to Bell for landing some decent shots. Plus Bell looked like he had just a little bit more in the tank than Carcillo did.
Hard to give it to Bell because I don't think he is very good but Carcillo threw some sucker punches and Bell thumped him for it and threw him down. Carcillo should stay in his weight class and fight the Tuckers and Averys.
