After trading away Max Unger and losing James Carpenter in free agency, one of the Seahawks biggest holes remained at offensive line heading into 2015.

Their first preseason game against the Denver Broncos only confirmed that notion, as the offensive line allowed seven sacks and 13 quarterback hits.

This forced the coaching staff to experiment with a different lineup in practice on Monday.

Garry Gilliam and Drew Nowack took starting reps at right tackle and center with the first team, respectively. Justin Britt, who had been starting at right tackle, moved over to left guard.

Meanwhile, Alvin Bailey, who was expected to take over at left guard for the departed Carpenter, was playing left tackle with the second unit.

"We'll see how the week goes. What we're trying to do is get the best guys out there in the huddle and then figure out where they fit," he said. "Right now, I think Garry has had a real nice camp and then put it together Friday night. It showed up pretty good."
