I think we should try to bring back Kelvin Beachum. He isn't very good but he's a good locker room guy and he can start at either tackle spot.
Ryan Kalil, Brian Winters, Brent Qvale, and Brandon Shell all need to go. Alex Lewis and Jon Harrison can compete for starting jobs, but are probably better off as quality depth on the interior. Nothing wrong with that. I'm cool with Tom Compton coming back as depth too.
It's essential that Joe Douglas comes away with at least one starting lineman in free agency and at least one more in the NFL Draft.
