If NFL teams are in training camp, it must be time for Hard Knocks. The first episode featuring the Atlanta Falcons kicks off tonight at 10 p.m. ET on HBO.

The show always delivers, as Hard Knocks pulls us in with story lines about obscure rookies trying to make the team and incredible access. It is a glimpse behind the curtain.

From a TV viewing standpoint, it is the best thing about the NFL’s preseason.

NFL.com has a teaser to the first episode.

A teaser clip from Tuesday’s premiere, featuring an entertaining skirmish between defensive end Kroy Biermann and rookie offensive tackle Jake Matthews.

“You hit me in the face again, 70, you see what the f— happens,” barks Biermann, now officially on our radar as a potential breakout star of the season.

An amused-looking Matt Ryan and Julio Jones are shown taking in the mini-brawl from a safe distance.

“Biermann and Jake … first day,” the quarterback deadpans.

It appears as if Falcons owner Arthur Blank, no stranger to the TV cameras, wants to be one of the stars of this year’s Hard Knocks. D. Orlando Ledbetter of the Atlanta Journal-Constitution writes:

Falcons owner Arthur Blank has been at camp for the last eight days, a franchise-record. In the past, he usually just drops by for a few days, he said on SiriusXM’s NFL Radio last night.

We’re pretty sure that he’ll be on the show.
