Tennessee Titans head coach Mike Vrabel is calling out the NFL and its officiating in a hilarious way.

Following a week of NFL games that had officials being publicly criticized for their errors (specifically on roughing the passer penalties), "the league emailed an officiating video to all coaches and general managers, as it does on a weekly basis," according to Adam Schefter.

It's not unusual for teams to receive videos of this sort, as the league will often reach out to teams following games to provide explanation for penalties called during the previous game.

This time, though, Vrabel took it upon himself to respond to the email. The Titans head coach put his frustrations into a hilarious passive aggressive message that let the league know how he really feels about the officiating around the league.

Here's what Vrabel's email said:

"I appreciate the time and energy that goes into these videos, but I suggest we devote every minute of our officiating departments' time ensuring our officiating crews are as well trained in the clarifications we worked to create in the off season and that each crew is as consistent as possible. Thank you."

If that wasn't funny enough, Schefter reported that Vrabel intentionally hit "reply all", meaning he responded to not just the league office, but delivered his message to every head coach and GM around the NFL.

Never change, Mike. Someone had to say it.
