(Renton, WA)  --  The NFL Network is reporting that Seattle Seahawks star running back Marshawn Lynch considered retiring if the team won the Super Bowl.  The report quotes a source as saying Lynch told teammates last season he would seriously consider calling it quits if the Seahawks won the world championship.  Lynch is reportedly dissatisfied with his current contract, under which he's slated to earn five-point-five-million dollars in base salary in 2014 and up to three-and-a-half-million in bonuses.  It was reported earlier this week that Lynch could skip all or part of next week's three-day minicamp.
