Sims was still finding his way after moving from left guard last season to right guard this season. He was hardly an established player, but the Seahawks liked his potential. They wanted him to get comfortable and develop under new line coaches Mike Solari and Mike DeBord.
Veteran Floyd Womack becomes the likely replacement for Sims, but his long and varied injury history suggests the Seahawks aren't finished shuffling their offensive line. Mansfield Wrotto will back up Womack.
Ray Willis, currently starting at right tackle for the injured Sean Locklear, arguably qualifies as one of the five best linemen on the team. But the Seahawks appear likely to leave him at tackle for now. They tried him at guard in practice previously.
Parker, meanwhile, rounds out a patchwork group of receivers. He caught 110 passes for Kansas City over the last four seasons. Parker becomes the Seahawks' speed receiver. Billy McMullen, signed Tuesday, becomes the bigger target. Deion Branch and Bobby Engram remain sidelined with injuries. Nate Burleson and Ben Obomanu are out for the season.
Receiver Jordan Kent could land on the practice squad after Seattle waived him. The Seahawks liked what Kent showed in camp, but they didn't envision him as one of their top three wideouts. The role was too much for him, which isn't a shock.
