"It's not all about money for me", he says.
Mathieu, who has 11 interceptions and one Pro Bowl appearance to his name, would certainly be a good fit for the Chiefs.
It was just 19 months ago that Mathieu-coming off a Defensive Player of the Year-caliber season that ended with a torn ACL-inked a five-year, $62 million deal in Arizona, the kind that has players thinking they'll finish their career in the place they started it.
The Jets would be wise to stay away from Mathieu since they don't have a need for another safety and even though he could potentially play cornerback, it's not worth the risk. His absence was sorely felt as the team that went 13-3 and won the NFC West faltered down the stretch, barely getting past Green Bay in the divisional round before being routed by Carolina in the NFC championship game.
Mathieu was not only a huge contributor on the field, but off the field as well. Mathieu wound up making a little less than $22 million of that.
The Honey Badger's last two seasons with the Cardinals were not as productive as his 2015 season but Mathieu was still a solid contributor.
Last season, Mathieu played most of his snaps in the slot (696 out of 1,052), but he also spent 108 snaps close to the line of scrimmage at the linebacker level and another 175 snaps playing in a deep free safety role.More news: US Chamber of Commerce warns of 'destructive trade war' with China
Wide receiver Charone Peake #17 of the New York Jets is tackled by free safety Tyrann Mathieu #32 of the Arizona Cardinals after a reception during the National Football League game at the University of Phoenix Stadium on October 17, 2016 in Glendale, Arizona.
Mathieu was due for $18.75 million of his contract to be guaranteed when the league year began Wednesday afternoon.
The Cards, however, were dealing with a contract based on his excellent 2015 season, which Mathieu signed in training camp before the 2016 season.
After three seasons in Miami, and two under head coach Adam Gase, the team decided they have had enough. He also had a $5 million roster bonus owed on March 16.
Following his release, Mathieu exchanged Twitter posts with supporters.
But Mathieu, the Cardinals' third-round draft pick in 2013, doesn't appear to be bitter about the development, as he sent a thank-you note to the Birdgang on Wednesday afternoon.
