There's plenty of reasons why the Ravens are 0-3, but here's one that has nothing to do with the offense, defense or special teams.
They're suffering from the Curse of Coaches Past.
The Ravens have lost their first three games this season to teams led by head coaches who once worked in Baltimore.
In Week 1, the Ravens lost to Gary Kubiak's Denver Broncos, 19-13. Kubiak, of course, coordinated the best Ravens offense in team history last season.
In Week 2, former Ravens linebackers coach Jack Del Rio, now coach of the Oakland Raiders, beat his former team, 37-33.
And on Sunday, the architect of the record-setting 2000 Ravens defense, Marvin Lewis, directed his Cincinnati Bengals to a 28-24 win, their fourth straight victory over the Ravens.
So, if there's anything to this curse, the Ravens' Thursday night game in Pittsburgh against Mike Tomlin's Steelers might be their best chance to win before leaving for their second set of games out west this season.
After Thursday night, the Ravens turn their attention to the Cleveland Browns. They're coached by Mike Pettine, a former Ravens video assistant and outside linebackers coach.
