Kansas City Chiefs quarterback Patrick Mahomes signed a 10-year contract extension on Monday worth up to $503 million, ESPN reports.

Why it matters: It's the largest contract in the history of American sports and almost double the career earnings of Eli Manning, the highest-paid player by salary in NFL history.

  • "We're staying together ... for a long time. We're chasing a dynasty," Mahomes said in a video posted on Twitter.

The big picture: Mahomes' 12-year deal — a 10-year extension, plus two years on his current contract — is incredibly rare. The Dallas Cowboys' Tyron Smith is the only other NFL player with a contract lasting more than six years.

Zoom out ... Highest average annual contract value by sport, per ESPN:

  • NBA: Damian Lillard ($49m)
  • NFL: Mahomes ($45m)
  • MLB: Gerrit Cole ($36m)
  • NHL: Connor McDavid ($12.5m)

Special report: The NFL is back and weirder than ever

The Chiefs beat the 49ers in Super Bowl LIV on Feb. 2. One day later, the U.S. declared COVID-19 a public health emergency.

The big picture: A lot has happened in the 223 days since then, highlighted by Tom Brady's arrival in Tampa Bay via free agency and Joe Burrow's arrival in Cincinnati via the NFL's first-ever virtual draft. Teams aced the training camp protocols, but without any preseason games, expect to see some rust when they finally take the field for game day.

NIAID director Anthony Fauci told CNN on Friday evening that if "people are not wearing masks, then maybe we should be mandating it."

Why it matters: Fauci made the comments the same day the U.S. hit its highest daily COVID-19 case count since the pandemic began.

Sen. Kamala Harris appealed to Black voters in Georgia on Friday, urging them to "honor the ancestors" by casting ballots, and again calling President Trump a "racist."

Why it matters: The U.S. saw a significant decline in African-American voter turnout between 2012 and 2016, reaching its lowest point since 2000. Higher turnout among Black Americans this year could tip the balance in favor of Democrats in key battleground states, including Georgia.
