I only watched the Mitchell/Moffett fight, but I thought all three rounds were easy to score. Moffett did get a lot of takedowns, but he didn't do much at all with them. There was very little ground-and-pound and only a couple of submission attempts.
Mitchell got a knockdown in Round 1 and threatened with a triangle/armbar sequence. He easily won that stanza. Lots of grappling exchanges in Round 2 and Round 3. Moffett got the best of it in the second and had a very close D'Arce. The third was close, but Moffett didn't get much going while Mitchell was close with a rear naked choke.
I thought Moffett lost the fight by going for the third-round D'Arce. He wasn't doing much from half-mount, but he was winning. Going for the same submission that failed in Round 2 allowed Mitchell to scramble to Moffett's back and nearly get the stoppage. That exchange gave the fight to Mitchell.
