Patrick Mahomes signed the highest-valued contract in American professional sports in July when he struck a 10-year, $450 million extension with the Kansas City Chiefs.

Baltimore Ravens defensive coordinator Don "Wink" Martindale, who faces Mahomes on Monday night, considers that a bargain.

"They could've paid him a billion," Martindale said Friday. "I'd still think he's underpaid."

Martindale has a lot of respect for the reigning Super Bowl MVP because Mahomes is the one quarterback who has consistently gotten the better of Baltimore.
