Exactly. Dirrell landed the cleaner and harder shots and looked the better of the two. He ran like a ***** but he was much sharper than Froch throughout the fight.
Froch didn't ruin his career. Kessler has had the same eye problems since before the Ward fight. All Froch did was lose (albeit close) to a deteriorated Kessler. Kessler backing Froch up and constantly hurting Froch to the body isn't ineffective aggression.
