Coming off their division-clinching home win over the Cardinals, the Seahawks flew to Bank of America Stadium for a Week 15 intraconference duel with the Carolina Panthers.  The game was scoreless until the fourth quarter when Seattle trailed on the foot of Panthers kicker John Kasay's 53-yard field goal.  The Seahawks would respond with kicker Josh Brown getting a 23-yard field goal.  However, Carolina began to pull away as Kasay nailed a 37-yard field goal and RB DeAngelo Williams managed to get a 35-yard TD run.  Seattle tried to rally as QB Matt Hasselbeck completed a 15-yard TD pass to WR Deion Branch.  However, the Panthers' defense held on for the win.
Question: How many yards longer was John Kasay's longest field goal relative to Josh brown's longest?
