The Seahawks defensive secondary played through some pretty serious injuries in the Super Bowl, as it turns out.
Earl Thomas played through a shoulder injury that now needs surgery, Kam Chancellor played with a torn MCL, which now needs surgery, and and Richard Sherman played with a torn ligament in his elbow, which now likely needs surgery. Of course, Jeremy Lane went out as well with a broken wrist, which will require surgery. Really puts in perspective how crazy of an effort a beat-up group of defensive backs put together against one of the greatest quarterbacks of all time.
Thomas will have surgery to repair a torn labrum in his shoulder (it's already scheduled), and as Pete Carroll mentioned, should be back and ready for the start of training camp this summer. Carroll mentioned over the past few days that he expects the rest of the Legion of Convalescence should be ready to go for next season as well, allying any fears that the Seahawks will miss their All-Pro group of players for any amount of time in 2015. As a league source told John Boyle, Earl "Will be good to go when needed for next year... Never missed a game. Will not change."
While the missed reps in OTAs and offseason training could have a slight effect at the beginning of the season, these are now veteran players, so that will certainly help with getting up to speed once they're cleared for contact.
