Tyler Shatley- played career high 643 snaps in 2020 w/ JAX. Was PFF's 14th ranked center (out of 36). 25 starts over the past 5 seasons.
Brett Jones- played 138 snaps in 2020 w/ MIN. Has started 19 games in 5 seasons with NYG and MIN (13 of those in 2017).
James Ferentz- played 161 snaps in 2020 w/ NE. Only 4 starts in 7 NFL seasons. Almost all his offensive snaps (365 of 387) have come the last 2 seasons. Turns 32 soon. Played for his father at Iowa.
Shatley would seem like a viable option to me. The others are pure depth guys.
