Andy Reid, head coach of the Kansas City Chiefs, is on track to become the NFL’s winningest coach in both regular season and postseason history. With long-term contracts for Reid and star quarterback Patrick Mahomes, the Chiefs have averaged 12.5 regular-season wins per year, putting Reid on pace to surpass Don Shula’s record of 328 wins in the 2029 season. Reid also needs just five more postseason wins to tie Bill Belichick’s record of 31 playoff victories and is projected to break that mark in the 2026 season. While Belichick could potentially challenge Shula’s record, Reid’s age and current team success favor his chances of becoming the NFL’s all-time coaching leader.
