EPISODE TWO: "FOG"

Episode Summary: The Cardinals were riding high with a 3-0 record, but as fervent fans know, the ensuing three-game stretch was turbulent. It opened with Arians asking his players to get his back after some trash-talk following a win over the Rams late in 2014, but the team played flat and dropped its first contest of the season, 24-22. Cornerback Patrick Peterson's health issues were touched on before the blowout win over the Lions – and he had an interception in that game to emphasize he was past them --  but the bulk of the episode focused on Arians' return to Pittsburgh to face the Steelers. There were some illuminating pregame scenes with Steelers quarterback Ben Roethlisberger and wideout Antonio Brown which showed just how much his former players love Arians. He left Pittsburgh with a loss, though, as the second episode concluded with the Cardinals at a bit of a crossroads.

Most Riveting Scene: It was fun to watch Arians in a time of crisis. Quarterback Carson Palmer threw an interception late in the Steelers game, and Arians was disappointed in the read.

He exasperatedly explained to Palmer what went wrong, but also realized there was time left. A few moments later, Arians called over wide receiver Larry Fitzgerald and told him the offense would get the ball back, and to make sure Palmer was mentally ready.

Something We Learned: Cameras rolled on the initial meeting between General Manager Steve Keim and outside linebacker Dwight Freeney as he joined the team at the Greenbrier in West Virginia. Keim explained his success rejuvenating the careers of older players, and then jokingly told Freeney he expected 10 sacks. It turned out to be prophetic, as Freeney led the Cardinals with eight sacks in 11 games. Freeney couldn't escape the age jabs, though. During Freeney's first practice, rookie offensive tackle D.J. Humphries ambled over to tell Freeney he did a project on him while in middle school.

Stars of the Episode: This one was centered around Arians, from his comments about the Rams to his Pittsburgh homecoming. Defensive line coach Brentson Buckner, one of the more entertaining characters, was also featured heavily.

Line of the Episode: "Kevin, you've got to get under now, because if he takes off running, there ain't no way in the world you're going to catch him. Because your car's back in Phoenix," – Buckner explaining the game-breaking speed of Steelers quarterback Michael Vick to Cardinals linebacker Kevin Minter.
