Dallas Cowboys The starters, who scored one touchdown in 12 preseason possessions, must get significant improvement from their offensive line. RT Marc Colombo is expected to return after missing all of preseason with a knee injury, which should help because backup OT Alex Barron is not a good enough run blocker to play that position.

Baltimore Ravens The Ravens have one of the most talented and balanced teams in the NFL, but the secondary will be their Achilles' heel. Starting CB Domonique Foxworth (torn ACL) is out for the season. Pro Bowl FS Ed Reed (hip) will miss at least the first six games.
