Seahawks coach Jim Mora has followed through on promises to shake up the offensive line following a poor showing Sunday.

Rookie right guard Max Unger will take over for Chris Spencer at center. Spencer has had snapping problems while battling a hand injury. His contract is up after this season. His future with the team beyond this season is certainly in question.

Spencer and Mike Gibson will share time at right guard. Unger was projected as a potential long-term center. I would expect him to hold the center job for years to come unless a need arises elsewhere.
