RAVENS PASSING GAME: Quarterback Joe Flacco played one of his worst games of the season in the team’s 36-21 loss to the Carolina Panthers, completing just 22 of 39 passes and throwing two interceptions. Flacco is down to 6.6 yards per attempt, better than last season but 30th in the league. He struggles when opponents bottle up his top deep threat, John Brown, as the Panthers did Sunday. None of the team’s receivers stepped forward in the blowout loss, as Willie Snead IV caught five passes on 11 targets and Michael Crabtree caught just three for 31 yards. The Ravens could be forced to play without one of their best pass blockers if Ronnie Stanley is sidelined by an ankle injury he suffered against Carolina.
