Coltsider broke down the game film and found that Anthony Castonzo's productivity wasn't as bad as it looked:
Overall, it seems that Castonzo’s play wasn’t as bad as it first seemed that it may have been. Castonzo started out slow, as four of those negative plays happened in the first seven pass plays. From there on out he only allowed one negative play, the Orlovsky fumble. If he has a weakness in pass protection, it’s an outside speed rush, but he’s usually ok with those. If he does get beat, he was doing a good job of pushing them wide and back. Unfortunately, the Colts’ quarterbacks have no pocket presence whatsoever, making it even harder for those offensive tackles.
