The Baltimore Ravens have been in the market for an offensive coordinator since Jim Caldwell took the Detroit Lions’ head coaching job.

After interviewing several candidates, the favorite for the gig is former Houston Texans coach Gary Kubiak, a mystery candidate who emerged over the weekend, ESPN’s Adam Schefter reports. The Ravens had also interviewed former Washington Redskins offensive coordinator Kyle Shanahan, former Texans offensive coordinator Rick Dennison and Ravens wide receivers coach Jim Hostler.

Schefter adds that Kubiak would want to hire Dennison and Shanahan in Baltimore, which would liven up the offense after the team failed to make the playoffs for the first time under Coach John Harbaugh. Kubiak, like Dennison and Shanahan, worked under Mike Shanahan in the past; Kyle Shanahan was Kubiak’s offensive coordinator in Houston.
