This is what I saw, too. Even though there was only one sack, Orton was feeling the pressure all day. In fact, I'd go so far as to say the poor Oline play has made Orton a bit jittery, to the point where he made several poor throws when he probably didn't have to. He probably just thought he didn't have any time left and had to get rid of it -- when he may have actually had more time to throw.
