Depth Chart
Piecing all of that information together, my best guess is that a depth chart looks like this:
Starting offensive line:
LT: J.C. Latham
LG: Peter Skoronski
C: Lloyd Cushenberry
RG: Dillon Radunz
RT: Nicholas Petit-Frere
Roles for other offensive linemen:
Daniel Brunskill: Backup center
Saahdiq Charles: Backup right guard
Leroy Watson: Backup tackle
Jaelyn Ducan: Second backup tackle
John Ojukwu: Practice Squad
Until I see Charles finish training camp and the preseason healthy, I have to assume that Dillon Radunz is going to win the job based on his availability as much as anything else. Meanwhile, Daniel Brunskill will probably get a lot of work with the second offensive line as a center, which means that it is going to be hard to earn the starting guard job.
NPF is going to win right tackle because no one else has been strong enough to take it, but I think if you asked the Callahans and the Titans front office if they are happy with their decision at right tackle, they would say that they made a mistake.
Even though Ran Carthon picked Jaelyn Duncan at the top of Day 3 last year, this coaching staff has invested more into Leroy Watson and I think they will have him higher on the depth chart after a shaky offseason from Duncan.
Ojukwu has to show everyone that he is more than just a name on the page and he has to put together some strong tape in the preseason to earn anything more than a job on the practice squad.
