If your line doesn't give a crap enough to get within three feet of a defensive lineman and lets them deflect a pass like that, any QB is going to throw a bunch of interceptions. He threw that right into the lineman. He could've kept his arms down and it still would've been deflected. He just barely got it with both arms extended in the air. Brown and Kruetz made absolutely no effort to keep his arms down. Grossman had Davis wide open on the slant, too.
