We are carrying 10 offensive linemen. So probably one of them. If I had to guess either Mike Onwenu, humongous guard we drafted out of Michigan this year, or Justin Herron, tackle we drafted out of Wake Forest this year. Both had good camps, but probably not quite good enough to become the gameday back ups right now.
We also have a Danish guy we drafted last year, Hjalte Froholdt, who by all accounts seems to have taken the back up Guard and Center job and Yodney Cajuste, tackle prospect from last year, who is likely the back up Tackle. Both spent the full season on IR last year and have yet to see game action in the regular season.
Patriots have question marks at both tackle spots but especially right tackle. Cannon opted out and there's a very very very good chance that if any of the linemen we have now secure the RT job that they will hold on to it into the future and Cannon gets cut.
There's also the fact that LG Joe Thuney is on a Franchise tag and likely walks next season and that we will likely need more depth to cover that too in the future.
All reasons to keep more linemen this year and have them compete for as long as is possible. (though we definitely don't need 10 on active roster)
