Josh didn't TRY to do anything to him. He went for one take down the whole 15 minutes of the fight, Diego swept him, got his back and Josh got out of there.
It was a shitty fight and Koscheck pulled a "Quick Swick," but Diego tried to be a counter-boxer, but couldn't connect and kept circling. They are both to blame for that lousy fight.
But the post-fight interview made me a Koscheck fan.
