LISTEN: Seahawks O Line coach Tom Cable on shuffling the line, Britt to center Your browser does not support the audio element.

With the free-agent departures of Russell Okung and J.R. Sweezy, it was already pretty well known the Seahawks’ offensive line was going to take on a different look next season. Just how different is starting to come into focus.

Seattle has a lot of moving parts along the O-line heading into Organized Training Activities later this month, as Justin Britt is moving to center from left guard and Mark Glowinski is switching to right guard to left guard, Seahawks offensive-line coach Tom Cable said on Saturday’s edition of “The John Clayton Show” on 710 ESPN Seattle.

Those moves join Garry Gilliam’s switch to left tackle to replace Okung and the free-agent addition of J’Marcus Webb to play right tackle, along with the draft selections of Germain Ifedi (Texas A&M, first round), Rees Odhiambo (Boise State, third round) and Joey Hunt (TCU, sixth round).

“The thing I love about it is we’re going to be spaced right in our level of maturity in the system and our background of it,” Cable said, “and then we plug in some young guys with it. It should be fantastic.”

This is the third consecutive season with a position change for Britt. A second-round pick out of Missouri as a left tackle in 2014, he was the starter at right tackle his rookie year, then shifted to left guard before the 2015 season.

Cable said it was Britt’s experience with the Seahawks that led the move.

“I think that’s what enables us to do it, the fact that he is well-versed in our system two years now,” Cable said. “He’s played tackle, he’s played guard, kinda understands it. The issue for him will be getting him comfortable and confident snapping.”

Britt’s main competition at center will be Patrick Lewis and Hunt.
