OWINGS MILLS, Md. -- The Baltimore Ravens hired Mike Macdonald as their new defensive coordinator Thursday night, creating some team history in the process.
Macdonald, 34, becomes the youngest coordinator in the franchise's 26-year existence, taking over a defense that has built a reputation for ranking among the NFL's best. He's believed to be the youngest defensive coordinator in the league.
This also marks the first time the Ravens have hired a defensive coordinator outside the organization -- although this is more of a reunion. Working under both Harbaugh brothers -- going from Jim to John -- Macdonald was the University of Michigan defensive coordinator last season after coaching for seven seasons in Baltimore.
