The thing about Kampmann is he lost it in all three rounds.
Round 3 - he was gassed and bleeding, made it seem like Deigo had more damage than maybe he had.
Round 2 - it was a close round that had he gone for take downs or submissions he might have pulled it off.
Round 1 - He was winning but once he starting picking Deigo apart he was doing it in a counter punching mode. He could have pulled a 10-8 or a finish if he was aggressive.
I think with the busted hand in rd 3, his gameplan went out the window and he felt he had to avoid Diego as best he could. Diego definitely hurt him in rd 2, so I think with the injury, he gambled on being evasive and lost.
