The NFL’s ultimate go-to guy. Though he may have had a drastic reduction in catches (17 for 184 yards), Brown reinvented himself as a nickel back and posted 17 tackles and three interceptions. He also found time to return 12 punts for 83 yards. Asked if he’s willing to wear all three hats again next year, Brown left no doubt. ‘‘I’ll do whatever Bill [Belichick] asks me to do,’’ said Brown. ‘‘I’m here to help this team win.’’ Win Super Bowls, that is.
