San Diego has three options: 1) release Tomlinson and save upwards of $6 million; 2) try to trade LT for a middle-round draft pick; or 3) renegotiate his contact to decrease the cap hit. The team will attempt strategy No. 3 before it seriously considers Nos. 1 and 2.
It's unlikely that both LT and Sproles will return, meaning Michael Bennett will probably ascend to the No. 2 role. Bennett was impressive when pressed into duty during the postseason, averaging 6 ypc and 6.5 yards per reception. Always known for his track-star speed, the eight-year veteran has become a much more patient runner as his career has progressed.
An intriguing player to watch is Eldra Buckley, who has spent the last two seasons on the practice squad. Buckley, who piled up 2,437 yards and 18 touchdowns during his collegiate career at the University of Tennessee-Chattanooga, is a do-it-all player who is a powerful runner and an adept receiver out of the backfield. To make the active roster, he likely needs both LT and Sproles to depart.
If the Chargers choose to address the running back position in free agency, they will keep a close eye on what happens in the New York Giants' backfield. Brandon Jacobs and Derrick Ward, both of whom topped 1,000 yards rushing last season, are scheduled for unrestricted free agency. Other free agents of note are LaMont Jordan (New England Patriots), Rudi Johnson (Detroit Lions), DeShaun Foster (San Francisco 49ers) and Aaron Stecker (New Orleans Saints).
If the Chargers go with a running back in the first round of the draft, the candidates are Knowshon Moreno (Georgia), Chris Wells (Ohio State) and LeSean McCoy (Pittsburgh), likely in that order. Later prospects include Rashad Jennings (Liberty), Jeremiah Johnson (Oregon) and Andre Brown (NC State).
