Jones has trained a lot with his older brother, one of the most popular fighters in a growing sport. He attributes quicker hands and feet to mixed martial arts training.

"I work out with him faithfully on hand fighting, wrestling, leverage," Arthur Jones said. "Just having good pad level is a game-changer in this league."

Jones almost didn't reach this point, though, dealing with an unexpected heart issue in August. The condition cleared up only sidelined him for the season opener but he has played every game since.

Overcoming an irregular heartbeat has given Jones a newfound appreciation for his sport and his burgeoning status.

"Yeah, I'm definitely grateful," said Arthur Jones, who grew up in Endicott, N.Y. as the son of a pastor. "It wasn't that many weeks ago where I thought my days were numbered from playing. It's just a blessing that God isn't through with me on the football field. Faith is huge in my family."

As is success for the three Jones' brothers. Jon Jones has reached the pinnacle of UFC. The youngest brother, Chandler Jones, is a New England Patriots starting defensive end drafted in the first round last year.

Arthur Jones has already earned a Super Bowl title. Now, he's approaching a financial windfall after entering the NFL on a relatively modest three-year, $1.447 million deal.

"You've got to put the work in, and I've done a pretty good job of showing I'm a great player in this league," Arthur Jones said. "It's a blessing to play in a great organization that let me play a lot and learn a lot."
