The Indianapolis Colts still have a few assistant coach openings on their staff, though it sounds like they've filled another one. According to Sports Illustrated's Thayer Evans, Arkansas running backs coach and special teams coordinator Jemal Singleton is heading to Indianapolis to become the Colts' new running backs coach.
Singleton spent one year at Arkansas, as he was hired in 2015 and saw immediate success. Running back Alex Collins had a tremendous year that prompted him to declare for the NFL Draft. Prior to his time at Arkansas, he was the running backs coach at Oklahoma State for four seasons (2011-2014). He was a long-time Air Force assistant coach, spending eight seasons there. He was a varsity assistant from 2003-2005, then the running backs coach from 2006-2010. In addition to coaching running backs, he also had the title of run game coordinator for four seasons (2007-2010). In each season as Air Force's run game coordinator, they ranked in the top ten in the country in rushing. He previously had played at Air Force, earning three letters as a halfback and becoming one of just six Air Force players to be named a captain twice.
It seems that Singleton is a well-respected and good coach, so hopefully his addition will help the Colts' running backs. Frank Gore is a veteran who has produced at a high level in the NFL, but after that the Colts have some younger, less experienced players, and hopefully Singleton will especially be able to help those guys develop. The Colts now have one more true vacancy on their coaching staff (tight ends coach), though they could always choose to add other coaches at areas to bolster the staff even more.
