Either Shanahan or Hostler will be tasked with improving an offense that ranked 29th in the NFL in 2013. Joe Flacco had an inconsistent season under center after winning the Super Bowl, and the Ravens couldn't sustain a viable passing attack on a week-to-week basis.
Kyle Shanahan (Mike Shanahan's son) re-energized the Redskins' offense, creating a dynamic attack led by quarterback Robert Griffin III in 2012. However, one year removed from the NFC East title, the Washington offense sputtered and both Kyle Shanahan and his father were run out of town.
Hostler hasn't been an offensive coordinator since 2007, when he ran the 49ers' offense. He's held the receivers coach job with the Ravens since 2008, so he's quite familiar with the players and key components in Baltimore.
UPDATE: Rapoport reports that Gary Kubiak has emerged as a candidate for the Ravens' offensive coordinator position. Kubiak was in discussions with the Cleveland Browns for their open OC position, but the former Texans coach wanted more power than the Browns were willing to give.
The big question facing the Ravens: Do they want some sense of continuity or is it time to start from scratch?
