This is not a "2nd string QB is better" threads. But Costello seemed to have something physically wrong with his shoulder. He was stretching during the middle of drives and his throw was definitely less accurate than last week. I also noticed that we didn't attempt a single vertical. It makes me wonder if Costello wasn't a little injured. It would explain not risking the impact for the first down, especially when there's no #2. Having a #2 if needed might change some decision making.
