What I saw was a "newcomer" who is smaller in stature control the fight from bell to bell. This was the same tactic Carwin and Brock used on Mir, as another poster mentioned the same tactic Mir used against Crocop. Randy and GSP use clinchwork all the time to get their takedowns. Mir excels in the ground game so Cormier did the right thing.
He ripped a ton of body shots, knees, and hooks in the clinch. Mir landed a few nice knees and kicks. I felt DC could have finished if he wanted to or at least hurt Mir even more. His shots were at 50% - 75% power. He didn't want to get sloppy and get taken down. Think we all expected a TKO from DC, but he got the win.
DC is already the Grand Prix SF, KOTC and XMMA champ. Titles don't mean much, but his list of fighters does considering his experience in MMA. If JDS was the HW champ he should get the shot, but given the scenario it's time for him to move south of the border for the title.
