Back-to-back Super Bowl championships and three titles in a five-year span prompted the Kansas City Chiefs to reward their top brass with contract extensions on Monday.Coach Andy Reid, general manager Brett Veach and club president Mark Donovan received what the club termed as long-term deals, though specifics weren’t announced.According to NFL.com, Reid got a new pact that runs through 2029 and makes him the league’s highest-paid coach.”Mark, Brett and Andy have achieved historic success together, and we are thrilled that they will continue in their roles for many years to come,” Chiefs chairman/CEO Clark Hunt said in a statement. “Individually, Mark, Brett and Andy each represent the best in the National Football League at their respective positions, and together, they make up one of the finest leadership teams in all of professional sports.”They have been tremendous leaders for this organization on and off the field, and we look forward to their continued success in the years ahead.”Reid, 66, has been on the job since 2013, compiling a 128-51 regular-season record and a 16-7 playoff mark in Kansas City. He has led the Chiefs to the playoffs in all but one of his 11 seasons.
