The Ravens have beaten every NFL either in the regular season or postseason except one -- the Carolina Panthers.
All three regular-season meetings have been won by the Panthers. The Ravens lost at Carolina in 1996 and 2002 before falling to the Panthers at M&T Bank Stadium in 2006.
Other than the Panthers, the only team the Ravens haven't beaten in the regular season is the New England Patriots. But the Ravens notched their first win over the Patriots last season in the playoffs.
