There is one fewer head coach vacancy in the NFL. The Tennessee Titans officially hired former Texans defensive coordinator Mike Vrabel on Saturday evening.

This news has some impact on the Philadelphia Eagles. It was previously rumored that Eagles offensive coordinator Frank Reich was a potential candidate for the Titans. Now we know he won’t be hired there.

The Vrabel hire also means there’s really only one true remaining opening in the NFL: the Arizona Cardinals. A number of teams haven’t officially announced their head coach hires but the news has already leaked. That includes: Pat Shurmur to the Giants, Matt Patricia to the Lions, and Josh McDaniels to the Colts.

The Cardinals reportedly interviewed both Eagles defensive coordinator Jim Schwartz and quarterback coach John DeFilippo this month. Flip is scheduled for a second interview in Arizona, although that can’t take place until Jan. 28 at the earliest if the Eagles beat the Vikings in the NFC Championship Game.

It’s possible the Cardinals hire a head coach before then. They’re reportedly enamored by Panthers defensive coordinator Steve Wilks.

It’s been rumored that Wilks could hire Flip as his offensive coordinator. Flip’s contract is up once Philly’s season is over, so the Eagles can’t block Arizona (or any other team) from hiring him.

As long as the Eagles’ season is still going on, teams will have to wait to hire any of Philadelphia’s assistants. If the Eagles do indeed make it to Super Bowl 52, that’ll leave other teams waiting until February.
