Assuming they don't make a trade, the Chargers will have a very interesting dilemma with their pick in the first round of the NFL draft. Selecting 18th, the team will likely be able to choose among three positions of need — wide receiver, offensive line or pass rusher. This year's draft class isn't loaded with lots of high-first-round talent at any of those spots, so good prospects at all three positions could be on the board when GM A.J. Smith has to make a call. Though pass rusher has long been an issue the team has tried to address, and receiver could be a priority if Vincent Jackson departs in free agency, we hear that offensive line may be Chargers' top target. With OG Kris Dielman announcing his retirement and OLT Marcus McNeill expected to be cut before free agency, the team will need to overhaul the line, especially on QB Philip Rivers' blind side. Expect Smith and the Chargers to draft more than one offensive lineman come April.
