The following is a position-by-position listing of who practiced where, with two cautionary notes. First, as has been the case since last fall, the backup defensive tackle rotation had veterans Quay Evans and Nick James taking the third- or even fourth-unit turns in both position drills and full-team competition. This was also done in their freshmen years but come the season both played as immediate backups, so don't read too much into this early-camp status again.
Second, the outside receivers alternations were very much in flux all practice, especially so with the younger and newest members of the unit. The first two or three at each split end position are essentially equal; after that everyone flipped side-to-side so the depth chart is purely for conversation purposes.
The defensive right or left designations here are based on the direction each player faced, and not where they will play. Cornerbacks for example are 'field' or 'boundary' rather than assigned a permanent side.
Any unlisted names were either simply overlooked, or yet to report officially.
