RICHMOND, Va. -- The Washington Redskins have rotated their defensive linemen all summer, making it hard even for that group to know what’s going on. So their an unofficial depth chart for the preseason opener clarifies only a little bit what’s happening up front.

The Redskins released their first depth chart of camp with the Baltimore game being played Thursday.

It’s an unofficial depth chart. It’s also true that it doesn’t matter until the regular season begins. But it does provide an early look at some position battles.

Defensive line: The "starters" listed were Stacy McGee and Ziggy Hood at ends and Phil Taylor at nose tackle. A.J. Francis was the No. 2 nose with Joey Mbu third. Rookie end Jonathan Allen was with the No. 2 defense.

What it means: A little, but not a lot. The Redskins have rotated their line throughout the spring and into training camp. It’s clearly kept players guessing as to where they fit on the depth chart. It has also given players a chance to work against different players in practice -- so players who would be considered backups can prove themselves vs. starters. The Redskins plan to rotate their line quite a bit this season, but that’s how they’ve done it the last few years. If Taylor does win the job, it would be a terrific comeback story after he missed the last two years due to various knee issues.

Inside linebacker: There is no surprise here as Will Compton and Mason Foster remain the starters, ahead of Zach Brown.

What it means: The Redskins don’t believe all the issues vs. the run started at inside linebacker, which is why they continue to have Foster and Compton in this role. However, Brown will rotate with the starters -- both next to Compton and Foster at various times. Sometimes it'll be in a nickel package; other times in their base front. He’s an athletic linebacker who can help. The question will be when and in what role. It’s certainly still possible he could end up starting. During the spring, Brown, signed in April, said it would take him into camp to feel comfortable in the defense. If that’s the case, he’ll show it in games and, perhaps, win the starting job.

Running back: It’s an easy call here with Rob Kelley and Chris Thompson the top two, with rookie Samaje Perine third (and the primary backup to Kelley). Former starter Matt Jones is fifth, behind Mack Brown.

What it means: The coaches like Kelley, and Perine still has work to do in order to become a starter -- notably in the passing game. Jones was on the outs in the spring, so him being in this spot isn’t surprising. It’ll be interesting to see if the Redskins backs are more consistent this season.

Outside linebacker: Rookie Ryan Anderson is listed with the third defense, behind starters Ryan Kerrigan and Preston Smith and backups Junior Galette and Trent Murphy. In fact, with Smith sidelined due to an ankle injury, it was Murphy who worked more with the first group Saturday.

What it means: The Redskins have good depth here. But they need it with Murphy suspended the first four games, so Anderson will get chances. But one note about the Alabama rookies, Allen and Anderson: I get the sense they don’t mind having to fight for positions; it’s how they were raised in college.

Receiver: The Redskins listed three receivers among their starters: Terrelle Pryor, Jamison Crowder and Josh Doctson. They’re the clear leaders among the receivers. Pryor will start at the X position, where Pierre Garcon had played.

What it means: The Redskins haven’t always listed three receivers among their starters in the past, but it makes sense to do so, considering the way their offense has evolved of late. According to ESPN Stats & Information, the Redskins used a three-receiver look 72.3 percent of the time in 2016 -- that’s up from 66.9 percent in ’15 and 61.6 percent in ’14 (coach Jay Gruden’s first season).
