Scott Pioli, who helped build the New England Patriots teams that have won three of the last four Super Bowls, has agreed to a contract extension as the team's vice president of player personnel. Terms of the extension that will keep Pioli with the Patriots were not disclosed. Robert Kraft, the Patriots' chairman and chief executive, said Pioli ``has done a tremendous job managing our personnel department and overseeing the draft for us.'' Pioli, 40, joined the Patriots in 2000 along with coach Bill Belichick. The team won a Super Bowl title in Pioli's and Belichick's second season in New England. Since that victory, the team has repeated as Super Bowl champs two more times, including this year's 24-21 victory over the Philadelphia Eagles.
