Dent had a decent guard. He got guard back fairly quick too when he got passed. I also thought that he defended the GnP well too. Lawson just didn't dish it out the way, I think, he's capable.
IMO Dent may have won the fight, but in the long run Lawson has the ability to become a better fighter. Dent is uncoachable in alot of ways. I know coaches around here that wouldn't put him in the cage with an attitude like he has during training.
