I don't think he used his height and reach enough. That jab should have stayed out there for the entire fight. And Diaconu was able to gamble, get inside and hurt Dawson a number of times so his defense can use some work and, like I mentioned with the jab, he needs to keep that hand out there and stop pawing with it.
I really think this guy needs to step up. He doesn't seem hungry enough and appears inconsistent.
And I actually thought that fight should have been a draw.
