Ravens assistant Hammock to become Northern Illinois head coach

The Ravens are losing another member of their offensive coaching staff as running backs coach Thomas Hammock will become the head coach at Northern Illinois.
Hammock, 37, arrived in Baltimore in 2014 and guided four different backs — Justin Forsett, Terrance West, Alex Collins, and Gus Edwards — to lead the Ravens in rushing over the last five seasons. He returns to lead his alma mater where he rushed for 2,432 yards and 25 touchdowns from 1999-2002 and served as the running backs coach from 2005-06. Hammock also coached at Wisconsin and Minnesota before breaking into the NFL with the Ravens.
His departure comes a week after head coach John Harbaugh promoted assistant head coach and tight ends coach Greg Roman to offensive coordinator. That move prompted Marty Mornhinweg to leave the organization despite being asked to remain under a different job title.
With Hammock gone and Bobby Engram expected to become the tight ends coach, openings remain at the running backs and wide receivers coaching positions. It remains to be seen whether Harbaugh will hire another assistant to focus on the passing game, a role that had been earmarked for Mornhinweg after he was demoted from offensive coordinator.
