Patrick Mahomes just signed a 10-year, $503 million extension with the Kansas City Chiefs, giving him the largest contract in NFL history.

While there never seemed to be any doubt that Mahomes would remain in Kansas City, the superstar quarterback says that head coach Andy Reid was instrumental in convincing him to essentially agree to become a Chief for life:

“Very,” Mahomes said of Reid's importance, according to Jeff Kerr of CBS Sports. “When you have a great organization from top down, from ownership to personnel, to general manager, to coaches, to players, — we do stuff the right way. With Coach Reid building that culture of how to play football and how to just be people and how to have a culture of winning while at the same time just being great people to each other — that gave me the security to know that this is going to be something that's going to be good for a long time.”

Reid took over as Kansas City's head coach back in 2013, four years before Mahomes was even drafted.

Since taking the reins, Reid has gone 77-35 with four AFC West division titles and six playoff appearances overall. Most importantly, Reid led the Chiefs to a Super Bowl championship this past season.

“Knowing that having a guy (Reid) that has built it the right way that I can keep carrying on that same culture in the locker room as much as possible,” added Mahomes.

Mahomes won the NFL MVP award two seasons ago and is coming off of a 2019 campaign in which he played 14 games and threw for 4,031 yards, 26 touchdowns, and five interceptions.
