Which member of the Legion of the Boom will be the last to leave?

The fourth member of the Legion of Boom, the annual recipient of the Brandon Kemar Browner & Byron S. Maxwell Memorial Scholarship, continues to rotate every time a new class of freshmen enters the Pete Carroll School of Defensive Backing.

The other three members do not. Rotate.

There are three eternal Seattle Seahawks who will play forever, work forever, live forever. They will never know retirement, old age or death.

Or, or, or, one of them will hang up his cleats, then the other, though neither one figures to do so quite as ceremoniously, awesomely or falsely as Marshawn Lynch.

Which extraordinaire Legionnaire, which bringer of Boom will then remain? The one who outlasts the other two?

Earl Thomas is signed through the 2018 season. His 2014 and 2016 ended with serious injuries to the missile he calls a body. He famously admitted, in public, that retirement crossed his mind after the season-ending broken leg last year.

Kam Chancellor, as you might have heard, is contractually a Seahawk through 2020. But his physical style of play appears conducive to... not playing every single game in 2020.

Richard Sherman should be able to play at an elite level for a long time, should he choose. He’s competitive, driven, hard-working, and corneracks age relatively well. He also might or might not have been seriously shopped to other teams most this past offseason.

Who will last the longest here? Think of it as a sad, or happy, question.
