Sure, Patrick Mahomes' contract probably won't net him $500 million but let's think if it did. Let's think about what you could do with half a billion, WITH A B, dollars.
You could buy:
27 Bugatti La Voitures ($18 million each)
More than half a billion chicken nuggets
100 of these Nicaraguan islands that are for sale
Every console video game from the SNES to the Original Xbox 10 times
Four high tech roller coasters
But remember, the creator of Amazon, Jeff Bezos, makes $500 million every 36 hours.
