LAS VEGAS (AP) – Patrick Mahomes, Travis Kelce and Andy Reid have made the Kansas City Chiefs a dynasty. They’re already thinking three-peat. First, they had to become the NFL’s first back-to-back Super Bowl champions in 19 years. Mahomes made sure of it, leading another super comeback on the NFL’s biggest stage in America’s showcase capital. Mahomes threw a 3-yard touchdown pass to Mecole Hardman in overtime, and the Chiefs rallied to beat the San Francisco 49ers 25-22 on Sunday, becoming the NFL’s ninth repeat Super Bowl champs. With pop star Taylor Swift watching boyfriend Kelce from a suite, the Chiefs captured their third title in five years and joined some of the league’s greatest franchises.
