Man, it really sucks thats he had to do mandatory military time. He could have been a champ in my opinion. Very solid ground game and his standup was evolving.
His problem was that, as you say, he had a better ground game than his standup, but insisted on fighting on the feet a lot of the time. The worst underrated thing to have is a ground game - because that means people aren't getting to see it - and the best underrated thing to have is a chin - because it means you aren't getting hit much.
