The Legion of Boom, the stout defensive backfield of the Seattle Seahawks, could be missing three of its four starters from February’s Super Bowl loss to the New England Patriots.

Strong safety Kam Chancellor informed general manager John Schneider and team officials that he wants a new contract and is “strongly considering” a holdout, NFL Network reported Wednesday. Chancellor has three years remaining on the four-year extension he signed last summer.

Already the Seahawks are unlikely to have All-Pro free safety Earl Thomas. Cornerback Byron Maxwell signed with the Philadelphia Eagles in free agency, leaving only All-Pro cornerback Richard Sherman as a sure thing when the NFC champions take the field.

Even Sherman is recovering from injury after playing with a hyperextended elbow in the NFC Championship game against the Green Bay Packers and the Super Bowl defeat to the Patriots.

The Seahawks have bowed to training camp demands in the past, most recently working through a contract adjustment with running back Marshawn Lynch.

But there are multiple veterans in the queue for more money, with priority being given to quarterback Russell Wilson and middle linebacker Bobby Wagner. Wilson and the Seahawks are in talks to complete a long-term deal but the quarterback set an artificial deadline of Friday to finalize a new pact. Wagner, like Wilson, can become a free agent at the end of the 2015 season.

Defensive end Michael Bennett has asked the Seahawks for a restructured contract and, according to some reports, told the team he’d rather be traded than play under his current deal.
