The Chiefs made sure they will have Super Bowl MVP Mahomes around as long as possible. Mahomes agreed to a 10-year extension worth $503 million, according to his agency, Steinberg Sports. The deal is worth $477 million in guarantee mechanisms and includes a no-trade clause and opt-out clauses if guarantee mechanisms are not met. It is the richest contract in professional sports history, surpassing Mike Trout’s $426.5 million deal with the Los Angeles Angels. (AP Photo/Patrick Semansky, File)
