What's noteworthy from the Minnesota Vikings' first unofficial depth chart?

Co-backup quarterbacks and some interesting depth on the offensive line.

The first unofficial depth chart of training camp was released by the Minnesota Vikings on Wednesday and even though it's "unofficial" it reveals plenty of noteworthy rankings. 

Kellen Mond and Sean Mannion are listed as co-backup quarterbacks, while Jesse Davis appears to be winning the right guard battle. Garrett Bradbury is still atop the center position while Chris Reed is the backup left guard and rookie Ed Ingram is the backup right guard. 

The No. 4 receiver job may currently be in the hands of Ihmir Smith-Marsette, who is listed ahead of Bisi Johnson, Myron Mitchell and Monday night's practice standout Trishton Jackson. 

If Irv Smith Jr.'s thumb injury prevents him from playing in Sept. 11 season opener, Johnny Mundt is the backup tight end. 

On defense, Danielle Hunter and Za'Darius Smith are listed as outside linebackers, which is their true role this season with the switch to a 3-4 base defense. 

Also of note on defense is that Cam Bynum is listed as the starting safety opposite of Harrison Smith, while rookie first-round pick Lewis Cine is Bynum's backup. Chandon Sullivan and rookie Andrew Booth Jr. are the top two backup corners behind Patrick Peterson and Cameron Dantzler.
