O-line changes for Ravens?

One of the big fears in Fantasyland as we headed toward the 2013 campaign was that Ray Rice's production would diminish, because the Baltimore Ravens would give backup Bernard Pierce a larger role in the backfield. As it's turned out, Rice's production has nearly evaporated, but Pierce has been a major disappointment, too. Rice, who has never averaged fewer than 4.0 yards per carry in a season, is averaging 2.8 YPC. Pierce also sports a 2.8 YPC, though he's at least rattled off a couple of 25-yard runs. Rice hasn't topped 14 yards on a carry in 2013.
