Now that salary cap-gate over, what's next for the Redskins 53-man roster. According to Rich Tandler- and without factoring in potential savings by cutting certain veterans -there is around 3.8 million left to play with, some of which goes toward signing the remaining draft picks. So, what should the Shanahan's do with that remaining coin? Considering the free agent options remaining are your rank and file types, we can probably ignore certain areas (defensive line, wide receiver, outside linebacker and - for now anyway - tight end and corner). Other trouble spots (inside linebacker, safety, running back, guardcenter) were addressed in the draft orduring the more vibrantportion of free agency though the depth chart is not set in stone. The Redskins drafted three offensive lineman, though not sure anyone thinks that means that problem area is completely solved.Tandler and I went point-counterpoint on the OL before the draft. While I like the attention given to the overall area during the draft - put me down now for saying fifth rounder Adam Gettis is the one to watch - not sure the starting right tackle spot and overall depth works for me. (If the NFL imposed cap hit impacted any single area on the team, you have to believe it was on the line. One has to believe once RG3 was in play, upgrading his protectors with veterans was a major priority, but once the dollars diminished, Plan B was inacted)Which brings us back around to the basis for this post: who's left on the open market. It's one thing to suggest more help is needed, butare worthy options available is the question. Here's a look at the top offensive linemen - heavy on the tackles - remaining in free agency:Marcus McNeill, OT (Chargers): Yep, he's still out there. Knee and neck injuries led to surgeries and missed games over the past two seasons, but when healthy, the 28-year-oldis a top shelf tackle option. With several teams still looking for tackle help - Falcons and Bears come to mind -McNeill will be snatched up once the next wave of free agency truly kicks in or before training camps open. With their (current) limited funds, not sure the Redskins can join the bidding.Kareem McKenzie, OT (Giants): Apparently even the 33-year-old right tackle is not sure what his football future holds. The 11-year veteran started al 16 games in four of the last five seasons for the Giants, but the Super Bowl champs are going with a needed youth movement up front (also, their line was not all that last season). As long as he maintains football shape, McKenzie is the kind of last second option a team could call one week and start the next.Jason Brown, GC (Rams): Went from being a top free agent after a strong run with the Ravens to one of the worst centers in the league. Considering the Redskins backup center hole and Kory Lichtensteiger is recovering from injury, Brown could be an interesting swingman target, though he might have better opportunities toland a starting gig elsewhere.Max Starks, OT (Steelers): This would be a sign-and-stash move as the 30-year-old tore his ACL during Pittsburgh playoff last season. If say Willie Smith shows the coaching staff enough to justify jettisoning Jammal Brown, perhaps Starks makes for a worthy signing with a look toward the second half of the upcoming season and 2013.Others: Jake Scott, G (Titans), Vernon Carey, T (Dolphins), Bobbie Williams, G (Bengals), Redskins in exile: Stephon Heyer (Raiders) and Derrick Dockery (Cowboys), still available.
