I re watched the 3rd and 4th quarters to see what was the difference. After the Ravens TD, they didn't get another first down until the last 30 seconds. In the TD drive, Seymour was held several times by Ogden. It was suttle, but it was there. Ogden, with his height was able to get his hands under Seymours shoulder pads and steer him.
Harrison was up in the box for several of the plays, but they had to expect the Ravens to try to bleed the clock with runs, as it is their MO.
But, on the interception, IMO, it was caused by Seymour collapsing the pocket. He beat the double team, Ogden and the Right Guard, splitting it, pushing back, so that Boller could not step into his throw. Boller couldn't get anything on the throw and had to short arm it. The throw ended up 5 yards short......
