The 25-year-old Davis recorded career highs in carries (68) and yards (240) in six games last season. He posted solid outings down the stretch, with a 64-yard effort against the Philadelphia Eagles and a 66-yard performance versus the Jacksonville Jaguars in December.
Davis also had 15 catches for 131 yards for the Seahawks, who boast a crowded backfield with Chris Carson, C.J. Prosise, Thomas Rawls, J.D. McKissic and Tre Madden. Quarterback Russell Wilson led Seattle in rushing last season with 586 yards -- 346 more than Davis.
