Analysis: The 27-year-old Spiller has spent his first five NFL seasons with the Buffalo Bills, showing the ability to pile up yards as both a ball carrier and receiver out of the backfield. His best season came in 2012, when he rushed for 1,244 yards and six touchdowns to go with 459 yards and two TDs receiving. He played in only nine games last season because of a shoulder injury, finishing with 300 yards rushing.
