Uh, he completed almost 70% of his passes for 300 yards and a TD. All his throws were down the field, no dump offs or screens at all. By terrible line you mean "he threw 2 picks", one of which went off a receiver's hands. He didn't have a great game but if you want a terrible line, go look up one of the rookies other than RGIII.
It's true Andrew Luck was awful yesterday.
