Countdown to Combine: San Diego Chargers OL

A closer look at the areas the San Diego Chargers could address in the draft. We'll continue Tuesday with a look at the offensive line, which is scheduled to work out Friday in Indianapolis.

Position of need: The Chargers started five different players at center and five different starting offensive line combinations in 2014. Longtime foundational players such as center Nick Hardwick and guard Jeromey Clary retired. Left tackle King Dunlap is scheduled to become an unrestricted free agent in March. So the Chargers will go through an extensive reshuffling up front during the offseason, and will to look to the draft for a versatile, young offensive line prospect.

Three players the Chargers could target in the draft:

T.J. Clemmings, Pittsburgh: At 6-5 and 307 pounds, Clemmings has the nimble feet, athleticism and long arms offensive line coaches covet for a cornerstone left tackle. However, Clemmings has only played two seasons on offense at right tackle in college and could be more of a long-term project. The Chargers don't have time to wait; the window is quickly closing to compete for a Super Bowl and San Diego needs someone to come in and perform at a high level right away. Clemmings could struggle initially against more experienced pass-rushers at the next level. I also wonder about his versatility, something San Diego offensive line coach Joe D'Alessandris values in his position group.

La'el Collins, LSU: At 6-4 and 308 pounds, Collins played solid against elite competition in the SEC at left tackle, but likely will be asked to move to right tackle or guard at the next level. He's a good run blocker who plays with a mean streak. A good but not elite athlete, Collins is more of a technician who played in a pro-style offense in college.

Andrus Peat, Stanford: At 6-7 and 312 pounds, Peat comes from a program known for putting out well-schooled offensive linemen who cut their teeth playing in a pro-style offense for the Cardinal. Peat is durable, appearing in 40 of 41 games during his three seasons at Stanford, including starting all 28 games in the final two seasons. Peat has the size and length teams are looking for from an offensive tackle prospect and can play right away. However, his ceiling isn't as high as Clemmings.
