GLENDALE, Ariz. — On Thursday night, Patrick Mahomes of the Kansas City Chiefs won his second N.F.L. Most Valuable Player Award, cementing him as the most accomplished passer of a new crop of young quarterbacks dominating the league. Three days later, he added the second Super Bowl victory of his career, throwing for 182 yards and three touchdowns to beat the Philadelphia Eagles, 38-35.
The game concluded a tumultuous season for the N.F.L. in which Buffalo Bills safety Damar Hamlin collapsed from a cardiac arrest on the field during a game and high-profile hits to Miami Dolphins quarterback Tua Tagovailoa renewed criticisms of how the league handles players’ health, especially concussions.
