One of the Legion of Boom’s various Ringo Starrs could be leaving the NFL after only six seasons.

Per a league source, Eagles safety Walter Thurmond is currently leaning toward retirement.

Last week, Les Bowen of the Philadelphia Daily News reported that Thurmond was considering walking away at age 28, after four years with the Seahawks, one with the Giants, and one with the Eagles.

Thurmond, according to the source, has opportunities to return, earning in the range of $4 million. But for now Thurmond is closer to calling it quits than coming back for a seventh season. Converted to safety last year by the Eagles after playing cornerback his first five seasons, Thurmond was selected by the Seahawks in the fourth round of the 2010 draft.

Thurmon, Brandon Browner, and Byron Maxwell each left Seattle via free agency after stints with Richard Sherman, Earl Thomas, and Kam Chancellor. None has spent more than one year with any team since departing Seattle.
