It's a brutal blow to Marshawn Lynch and the entire Seahawks' offense. Things were already looking down after they lost starting RG John Moffitt (knee) for the season earlier this week, but the loss of Carpenter, the No. 25 overall pick, is going to be tough to overcome. He was the only Seahawks' offensive player to play on 100 percent of the snaps this season. Look for Breno Giacomini to step in as the right side of his line has suddenly become a major liability
