I think the smart money takes the over and hopes Steve McNair stays healthy.  RB Willis McGahee is much faster than Jamal Lewis which should help the Ravens run more effective on the perimeter.  Also, look for the Ravens to take advantage of #3 WR Demetrius Williams’ explosive speed when teams cheat up to stop the run.  The defense will again be one of the best in the NFL due to the awesome talent they have in every unit.  Take the over with confidence.
