Christmas came early for New York Giants defensive end Osi Umenyiora. Friday night, ESPN.com learned Umenyiora had followed up the first Pro Bowl selection of his career earlier this week by agreeing to a landmark six-year contract extension. The extension, which runs through the 2012 season, totals just under $41 million and includes $15 million in guarantees. The three-year veteran, who is second in the league in sacks with 12?, will make about $21 million in the first three years of the contract. The deal, negotiated by the Manhattan-based agency Sportstars -- where Brian Mackler, Alan Herman, James Ivler and Jason Chayut are the principal representatives -- will be officially executed in the next few days. The guaranteed part of the contract is believed to be the largest ever awarded to a three-year veteran. "The Giants have always demonstrated a proactive stance with their talented, young players and this is the latest example of their approach," said Mackler, who was the point man in negotiations, but declined to discuss specifics of the contract. "This moves Osi into a category with the most elite ends in the game, and that's saying something for a player who hasn't even completed his third season yet."
