Quarterback Patrick Mahomes, one of the N.F.L.’s biggest stars, has signed a 10-year contract extension with the Kansas City Chiefs, according to a person familiar with the terms of the deal who was not authorized to speak for the team.
The big payday, worth up to half a billion dollars, for Mahomes, who at 24 has already been voted as the league’s most valuable player and won a Super Bowl, is likely to set a new benchmark for the league’s young quarterbacks who are also playing on rookie contracts.
