With less than a week until the team's Week 1 matchup with the Eagles at FedExField, the Redskins on Tuesday unveiled the first unofficial depth chart of the 2017 regular season.

When it comes to defensive lines in today's NFL, every lineman that is active on game days will likely see at least a few snaps. For the Washington Redskins, that means that the six linemen that are currently on the team's 53-man roster will have their number called by defensive line coach Jim Tomsula.

"I think it's become more specialized a lot," said Redskins head coach Jay Gruden last month. "You know, you've got first and second down. You've got base, you've got nickel, you've got dime, and you've got all these sub packages now that people have to run in and out. You know, we might only have one defensive lineman on the field at one time. Sometimes we'll have two, sometimes we'll have four, and sometimes we'll have five. So, you know, it's a very specialized group now and it calls for a lot of substitution."

On the first unofficial depth chart of the regular season for the Redskins, rookie Jonathan Allen and free agent addition Stacy McGee are listed as the starting defensive ends while veteran Ziggy Hood is the starting nose tackle.

Allen, of course, was the Redskins' first-round pick in the 2017 NFL Draft. A dominant player against college completion, Allen impressed during training camp particularly in 1-on-1 situations.

"He's extremely strong so you have to be very mindful of playing with a good base when playing against him," said five-time Pro Bowl tackle Trent Williams. "He knows not to get past quarterback depth, which a lot of young guys make that mistake. You run them by pretty easy. I was just impressed when he gets to the depth of the pocket he turns his rush back into you."

Rest of the depth chart

Here are some additional notes from the first unofficial depth chart this season.

Offense:
--The Redskins on Sunday claimed tackle T.J. Clemmings off waivers from the Minnesota Vikings. He is currently listed as the No. 3 right tackle behind Morgan Moses and Ty Nsekhe, who also serves as the No. 2 left tackle after Trent Williams. Clemmings comes to Washington after two seasons in Minnesota in which he appeared in 31 games with 30 starts.

--Tyler Catalina, meanwhile, is listed as the No. 2 left and right guard behind starters Shawn Lauvao and Brandon Scherff. Catalina originally joined the Redskins as a college free agent signing out of Georgia earlier this year.

--The three starting wide receivers remain the same from the preseason depth chart in Terrelle Pryor Sr., Josh Doctson and Jamison Crowder. There is one minor change to the depth here, though, as Doctson is also listed behind Pryor at his wide receiver slot.

Defense:
--Mason Foster (Mike) and Zach Brown (Mo) was the starting middle linebacker pair during Washington's second and third preseason games and remain that way on the unofficial depth chart. Foster played Mo linebacker last year, but has since switched over to the Mike linebacker position. He has previous experience calling defensive alignments during his time with the Tampa Bay Buccaneers. Will Compton and Josh Harvey-Clemons are listed behind Foster on the depth chart at the Mike linebacker spot while Brown is backed up by Martrell Spaight.

--Deshazor Everett is listed as the starting strong safety after Su'a Cravens was placed on the Exempt/Left Squad list on Sunday. Everett is in his third season overall with the Redskins but his second at safety. He started Washington's final three preseason games, recording nine tackles and a pass defensed.

Special Teams:

--Almost no changes here, as the team's three specialists didn't face any position competition during the offseason months and Jamison Crowder and Chris Thompson remain the starters at punt returner and kick returner respectively.
