Analysis: Simpson on Tuesday became the latest addition to a crowded backfield that includes rookie first-round draft pick C.J. Spiller, and Marshawn Lynch and Fred Jackson, who split the starting duties last season. Simpson was used mostly returning kickoffs with the Colts. He also added 30 carries for 147 yards and a touchdown before being released by Indianapolis last month.
