This is what Offensive Coordinator Eric Bienemy said about Lewis:
"We have him at left guard and he's done a heck of a job. He's very athletic. He can move. He's competitive. He's got that nastiness about him. He loves to have a ballcarrier running the ball behind him. The sky can be the limit for him. We've got Alex at guard and (David) Bakhtiari can stay at left tackle. But we want all those guys to be flexible, interchangeable."
