Over the past four years, every starter on the Seattle Seahawks defense has remained the same except for defensive tackle, corner opposite Richard Sherman, and now this year: SAM linebacker. The departure of Bruce Irvin left a big hole in the defense without having an heir apparent. Going into the preseason, it was Mike Morgan vs Cassius Marsh vs Eric Pinkins. Some through Kevin Pierre-Louis’ name around to be in contention, but he has mostly only played WILL, and wasn’t in the competition at SAM, due to having a smaller frame that is more suited to playing in space, and not up on the line of scrimmage.
