Mahomes gets 10-year, $400M extension

Kansas City and their Super Bowl winning star quarterback are set to be 'Mahomies' until 2031.
ESPN's Adam Schefter reports sources say Patrick Mahomes and the Chiefs have inked a 10-year, $400 million, contract extension.
Mahomes had two seasons and $27.6M left on his previous deal. Though, KC earlier indicated that an extension would be forthcoming, but not until after the conclusion of this season.
Is this a good move by KC? What does it mean for Mahomes' supporting cast? What's the biggest raise you've ever received?
