Depends on what one expects from a depth chart, dz.
For example, I see Cooper and Thomas as locks to make the 53. I even see Ccoper as likely starter in the slot. I see Quick and Marquez battling for the 5th and 6th spots with Williams and Spruce. Not even sure things to make the 53. Yet Quick and Marquez are listed ahead of Cooper and Thomas.
You already mentioned TJM listed as 3rd string. NOBODY would make that bet.
Harkey ahead of Higbee? Please...
Joyner is EXTREMELY unlikely to start at outside CB ahead of a healthy Gaines.
The depth chart is stacked with rookies behind vets and with no regard to actual realities.
A coach's depth chart would look far different, as we both know.
So, if one's goal is to predict likely pecking orders at these various positions, then this depth chart is absurd.
Might as well stack then alphabetically. Or by age. Lol.
