Top takeaways from episode one of "Hard Knocks"

What they're saying: "Chicago, home of the blues, deep dish pizza and lakeside summers," narrator Liev Schreiber says in the beginning of the episode.

Here are some takeaways:

• Not surprisingly, the first storyline surrounded rookie quarterback Caleb Williams. This included a botched karaoke performance in front of the team and a montage of Williams struggling in practice.
• Head coach Matt Eberflus' beard stole the show. The episode focused on an in-house haircut accompanied by a side-by-side comparison with Ryan Reynolds' facial hair.
• Jonathan Owens' excused absences to support his wife, Olympic star Simone Biles, was featured early. The cameras followed Owens and his dogs while he chatted with Biles on a video call.
• Theo Benedet made the biggest splash. The Canadian lineman butchered a karaoke version of "God Bless the U.S.A." while stripping down to his underwear. It was a bizarre scene that ultimately set up the rookie's injury that will sideline him throughout camp.

Honorable mentions: Legendary Alabama coach Nick Saban came by to give Eberflus a pep talk, quarterbacks practiced diving on on a Slip 'N Slide and the Eberflus family gossiped about backup quarterback Tyson Bagent's long hair.

Hyperbole alert: The narration slipped up toward the end of the episode. While showing a late touchdown from last week's preseason game, Schreiber said "Collin Johnson's laser sharp route and [Brett] Rypien's rifle right arm haven't just given the Bears the lead, but the whole city hope."

• Um, no. Johnson and Rypien are both backups who may not make the team.

The bottom line: The episode was short on training camp highlights and private moments fans rarely get to see, but it did a good job of setting up the storylines we'll follow throughout the series.
