Thomas could replace Michael Turner as the power back in San Diego's rotation. He is also an underrated receiver, having caught at least 15 passes in five of his seven seasons. For his career, he has 1,044 carries for 3,891 yards (3.7 ypc) and 23 rushing TDs.
OT L.J. Shelton
Shelton is nimble enough as a pass protector to play left tackle, and powerful enough as a run blocker to play right tackle. The Chargers need such a versatile player to provide depth behind Marcus McNeill and Jeromey Clarey. Last season's backups, Roman Oben and Shane Olivea, have both been released within the last five months.
On the defensive side of the ball, the Chargers' top needs are in the secondary. After losing Drayton Florence to the Jacksonville Jaguars and Marlon McCree to the Denver Broncos, the Bolts are in the market for some veteran backups.
On safety prospect to watch is Chris Crocker. SDBoltReport.com's Amberly Richardson wrote an article earlier detailing why Crocker is an excellent fit with the Chargers. This is still true nearly a month later.
At cornerback, the Chargers could look to pluck from a division foe by targeting Kansas City Chiefs cornerback Benny Sapp. In his four years with the Chiefs, Sapp has 103 tackles, 13 pass breakups and two interceptions. He is a bit undersized (5'9", 190 pounds) but has ample experience as a nickel back, which is the role he will fill with the Chargers.
