Pete Carroll confirmed the team's worst fears: Marquise Blair and Bruce Irvin will each miss the rest of the season with ACL tears. Both are crucial losses for the Seahawks defense.
We put some notes out earlier regarding Irvin.
As for Blair, it's devastating news for an up-and-coming player who had made an impressive transition from safety to nickel corner.
"Marquise was just breaking in for the first time and getting it rolling and really making a big splash to start the season," Carroll said on Monday. "We're feeling the loss."
Ugo Amadi will reclaim the nickel role in Blair's absence. Amadi had some nice moments as a rookie, but the lasting impression of his 2019 season was a rough game against the Packers in the Divisional Round of the playoffs.
He did step in admirably against the Patriots, though, totaling eight tackles, including one for a loss.
"He did well. He did a nice job," Carroll said. "He really was active. Ever since he's been on the field for us, whether it's special teams or when he plays (defense), he just shows up. He's got a great burst to get to the ball. He's a very active football player.
"We need him to step up and be a factor. He's filling some big shoes. Marquise had done a great job to this point."
The biggest question in the wake of Blair's injury is how it will impact Seattle's utilization of its nickel personnel. The Seahawks famously stuck with their base defense 30% more than the next closest team in 2019. That was due to a lack of faith in a nickel corner. So will they trust Amadi enough to give him Blair's full workload? Or will they find an alternative, like reverting back to a base-heavy approach?
It's inevitable that Seattle's defense will look much different in Week 3 than it did on Sunday against the Patriots.
