Wade Phillips' first year in the NFL was 1976 with the Houston Oilers, and he didn't win a Super Bowl until 40 years later.

He may only have one title in his career that spans parts of six decades, but he's a legend in NFL circles.

After helping the Los Angeles Rams to a Super Bowl appearance in 2019, Phillips did not get any NFL jobs for the 2021 or 2022 seasons.

Phillips, the head coach of the XFL's Houston Roughnecks, has a theory why he's not coaching in the NFL.

"I hate to say it, but I think it’s age," Phillips, 75, said, via the New York Post. "It’s hard to beat my record as a coordinator, so there’s got to be another reason. But that’s OK. I’m glad to be doing what I’m doing."
