According to ESPN NFL insider Adam Schefter, Patrick Mahomes’ new contract is, not only the largest contract in NFL history, but the largest in sports history as well.
The deal Mahomes just signed has surpassed Angels center fielder Mike Trout (426.5 million) as the largest contract in North American history.
According to Schefter: Patrick Mahomes had two years and $27.6 million left on his existing deal — $2.8M this year, $24.8M in 2021. His 10-year extension is worth over $400M, though it’s still uncertain how much over. So the lowest his 12 year-deal could be worth is $427.6 million. But will be more.
Looking at the extension length alone, Mahomes’ deal is five years longer than any other player in the NFL.
