Bob Sanders' big hits have finally paid off in a big way. The two-time Pro Bowler signed a five-year contract extension Friday, a deal that will keep him with the Indianapolis Colts through 2012 and makes him one of the league's highest-paid safeties. The deal is worth $37.5 million and includes $20 million in guarantees, a person familiar with the negotiations told The Associated Press on condition of anonymity because the deal had not yet been announced.
