Heading into the opening week of the NFL season, most Ravens fans were very worried about the offensive line.  Michael Oher was going back to RT, Bryant McKinnie was the new Ravens LT, Marshal Yanda went back to RG and Matt Birk had been hurt all preseason.  The only guy back and healthy was Ben Grubbs.  They looked incredible against the vaunted Pittsburgh Steelers defense and everyone breathed in and felt everything is going to be OK.  Boy were we wrong.  The line has been weak since.  Plus Grubbs has been hurt. They moved Andre Gurode in at guard and he’s been bad.  It’s funny but here we are at 4-2 and one of the Ravens biggest preseason worries is still and enormous concern
