Rarely does the year’s first depth chart reveal much about the roster composition of the Green Bay Packers.

The same premise holds true for 2017.

The Packers released their first unofficial depth chart on Sunday, and there were very few surprises.

Here are a few quick observations from the depth chart:

– Don Barclay is the backup center. His versatility along the offensive line makes him a valuable substitute. He’s also the backup long snapper.

– Don’t be fooled by the receiver and running back listings. Read the depth chart horizontally. For example, Jeff Janis is with the third-team offense, but he’s not behind the two draft picks (Malachi Dupre, DeAngelo Yancey). Read the chart horizontally first, and then vertically. Do the same with the running backs, where the order goes: Ty Montgomery, Jamaal Williams, Aaron Jones and so on. Devante Mays is not ahead of Jones. Nor does it really matter at this point of camp.

– Quinten Rollins and Davon House are listed as the starting cornerbacks, with Damarious Randall and LaDarius Gunter as the primary backups. Rookie Kevin King is with the third team, but the Packers have done plenty of mix-and-matching at corner.

– Jake Ryan and Blake Martinez are the starting inside linebackers, but Joe Thomas and Morgan Burnett (the starting safety) have played plenty of first-team snaps at the position at camp.

– The starting defensive line is Dean Lowry, Kenny Clark and Mike Daniels. Veterans Ricky Jean-Francois and Letroy Guion are listed as backups. That fits with how the Packers have lined up so far at camp.

– Randall Cobb is listed as the No. 1 punt returner, while Jeff Janis is the No. 1 kick returner. Trevor Davis is the No. 2 at both return spots. Cobb is also the backup holder.

For the most part, the Packers’ first unofficial depth chart is based on seniority. Don’t read too deep into any one listing. Training camp isn’t yet two weeks old, and the Packers haven’t even lined up to play a preseason game. More will become clear as camp rolls along and exhibition games are played.
