The Washington Redskins have many key pieces in place on offense. Quarterback, left tackle, top wide receiver, running back, tight end and fullback lead the way. But the unit has a number of deficiencies as well, and so general manager Bruce Allen & Co. will look to free agency and the draft to address these areas.

Free agency gets underway in just a few days. The negotiation window opens on Saturday, and then at 4 p.m. Tuesday, teams can sign players to contracts.

Here’s a look at some of the biggest holes on the offensive side of the ball, and how Washington could fill them. In case you missed it, yesterday we took a look at the defense.

Wide receiver

Pierre Garcon is firmly entrenched as the No. 1 receiver, but Washington needs to give Robert Griffin III more weapons. The Redskins need another outside threat to line up opposite Garcon because Josh Morgan is a free agent, and Leonard Hankerson faces an uncertain future as he recovers from a torn anterior cruciate ligament. Washington also needs a slot receiver with Santana Moss now a free agent as well. The Redskins could look to free agency to fill one role, and the draft for the other.

Top wide receivers available: Eric Decker, Hakeem Nicks, Golden Tate, James Jones, Julian Edelman, Andre Roberts.

Right tackle

Tyler Polumbus displayed improvement, but still had his fair share of struggles. The Redskins would like to add a more athletic, more powerful right tackle this offseason. Second-year pro Tom Compton worked as a backup swing tackle last season, and could contend for a promotion this offseason. But Washington still will likely look outside the organization to address this position.

Top tackles available: Anthony Collins (Cincinnati), Michael Oher (Baltimore), Austin Howard (New York Jets).

Interior linemen

The Redskins have opted for smaller, quicker interior linemen because of how they do better in the zone-blocking scheme. But Jay Gruden has made it clear the line needs some fixing. Center Will Montgomery and right guard Chris Chester struggled in particular last season. Those two, left guard Kory Lichtensteiger, and backups Josh LeRibeus and Adam Gettis remain under contract, but it would be surprising to see the Redskins not address this position in free agency. Some shuffling also remains possible. It wouldn’t be surprising to see Lichtensteiger move to center while someone else takes over at left guard.

Top guards/centers available: G Geoff Schwartz (Kansas City), G Rodger Saffold (St. Louis), C Evan Dietrich-Smith (Green Bay), C Brian De La Puente (New Orleans).
