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.

"Atmospheric river" swings Northern California from drought to flood

A series of powerful "atmospheric river" storms are delivering historic amounts of rainfall across parts of drought-stricken California and the Pacific Northwest.

Why it matters: The atmospheric river, packing large amounts of moisture, was causing Northern California to whiplash from drought to flood, as it slowly moved south overnight. It's triggered widespread power outages, flooding and mudslides.

A major storm system was pummeling Northern California and parts of the Pacific Northwest with heavy rains overnight.

The big picture: "Atmospheric river" storms, associated with a record-strong "bomb cyclone" offshore from the Pacific Northwest, have brought flooding and mudslides to parts of California that were razed by recent wildfires and in severe drought. It's also caused widespread power outages in California and Washington state.
