I don't blame the officials for this at all.
Let's not forget that not 1, not 2, not 3, but 6 different NFL head coaches gave the competition commitee proposals to allow expanded replay for penalties, so that situations just like this could be ruled correctly. The commitee refused to consider any of them. (They also allowed the four teams with openable domes to open them at the half, and Indy's half open dome directly impacted the Colts/Jags game. So much for competitive balance).
The back judge made a judgement call. He was wrong, but the tools to correct exist and are not allowed to be used. Don't blame the refs, blame the dinosaurs on the CC and the NFL's lack of common sense.
