As a practical matter, the end for the Legion of Boom came last November, when All-Pro free safety Earl Thomas rode off the field in Arizona with his broken leg in an air cast and his middle finger extended toward the Seattle Seahawks' sideline.
But Thomas' widely expected free-agent departure in March brought finality to a transition from one of the most loaded secondaries in NFL history to one that no longer has a single player with a Pro Bowl on his résumé. Right before Thomas signed with Baltimore, Seattle also lost Justin Coleman to Detroit, which made him the NFL's highest-paid nickelback.
