The Baltimore Ravens already made one major move to address their offensive line issues, but more must be done.
The team traded for left tackle Eugene Monroe and stripped Bryant McKinnie of his starting job, and while one game is too small of a sample size, the results weren't any different than any other week.
The Ravens don't have one of the league's top offensive lines, but on paper, it certainly shouldn't be one of the worst. Marshal Yanda is a Pro Bowl guard and Kelechi Osemele should be one as well, but his play has regressed.
Michael Oher is nothing special, but he should be at least a slightly above average right tackle, and Monroe is at least average on the left side and a major upgrade over McKinnie. Gino Gradkowski has been a disappointment and is a big drop-off from Birk, but the offensive line as a whole should be at least as good as last year.
The big question is why the offensive line, with generally the same pieces from last year, has become completely incompetent when it comes to run blocking and below average in pass protection.
All signs have to point to Juan Castillo, who was hired in the offseason to be the team's running game coordinator. Castillo made it known that he saw a lot of potential in the team's linemen and would really coach them up. So much for that.
I'm not sure if this is a case of too many cooks in the kitchen (do you really need a running game coordinator and an offensive line coach?) or Castillo simply doing a poor job, but it's time for the Ravens to address the elephant in the room.
John Harbaugh doesn't want to take any criticism, and he certainly has a habit of cutting ties with coaches far too late; see Cameron, Cam. This could be deja vu all over again, and there is no telling how many games it will cost the Ravens this time before they decide to part ways with a coach who clearly is having a negative effect on the team.
If nothing else, it's time the Ravens abandon the zone-blocking scheme Castillo brought with them and go back to the more basic schemes they used in the past.
