Report: Lions hiring former Colts running back coach David Walker

The Detroit Lions lost running back coach and run game coordinator Curtis Modkins to the San Francisco 49ers on Friday, but it would seem his replacement has already been lined up. The Lions have plenty of position coach vacancies to fill, and for the running backs they have reportedly looked towards David Walker, who worked with Jim Caldwell when both were employed by the Indianapolis Colts at one point.

Per Fox Sports' Alex Marvez:

Source tells @NFLonFOX that @Lions expected to hire David Walker as RBs coach. Walker was @Colts RBs coach 2011-14. History w/Jim Caldwell

Walker worked with Jim Caldwell in his final year with Indianapolis, and continued to coach in Indy with Chuck Pagano. Walker was fired in January 2015 and has not been employed with another NFL franchise since that time. Walker previously coached running backs at the collegiate level, at Syracuse and Pittsburgh.

Although the Colts offense did not rank well in rushing numbers since 2011 (often within the low-20s in rank), it's important to note that such is not an indicator of the job of a running back coach, moreso an indicator of talent, the run game coordinator and offensive coordinator. Still, early outlook on the hire seems to be that Walker is being brought on for his previous experience working with Caldwell.
