This is some Chris Kiffen type spin right here.
"Sylvester Croom enters his first season with the Titans as running backs coach and 22[SUP]nd[/SUP] as an NFL coach. He is no stranger to working with elite talent, coaching a who’s who of running backs in his time in the NFL, including Maurice Jones-Drew, Steven Jackson, Ahman Green, Barry Sanders and Eric Dickerson. Chris Johnson becomes the third running back Croom has coached who has surpassed the 2,000-yard rushing mark in a season."
Eric Dickerson topped 2,000 yards in 1984....when Croom was coaching linebackers for Alabama.
Barry Sanders topped 2,000 yards in 1997 with Croom as the OC.
Chris Johnson topped 2,000 yards in 2009....when Croom was coaching RBs for the Rams.
