It’s the time of the year where the coaching carousel spins wildly around the NFL. And for once, the Lions could be losing a coach because another team covets him.

Per a report from NFL.com’s Tom Pelissero, the Denver Broncos have requested permission to interview Lions defensive coordinator Aaron Glenn for their head coaching vacancy.

Glenn interviewed for the New York Jets head coaching position last offseason, and his name often appears in the head coaching watchlists. He was recently asked about the potential to become a head coach outside of Detroit.

“I want to be the best coordinator the Lions ever had. That’s all I think about,” Glenn said last week. “…Listen, this is a job that I have right now, and I want to be the best I can be at it. And I want to be the best that ever came through Detroit. I want you guys to say that at some point, that he was the best coordinator ever. That’s what my goal is.”

The Lions can refuse to allow him to interview, but that would require adding additional duties to Glenn’s title. Denver has also reached out to several other potential candidates, including former Lions quarterback Kellen Moore.
