I just caught the Siver/Phan fight online, and Siver looks damn good at FW. Although I'm not sure how much of that is him being good and Phan being solidly mediocre, he was still impressive. His cardio is solid, his timing on his counters is on point, he had some pretty sweet transitions on the ground, and he's a giant at 145. He needs to ditch the spinning back kick when he faces the wrestlers higher up in the division, though.
