What we learned about Kirk Cousins from Netflix's "Quarterback"

• Cousins meets regularly with the team's sports psychologist and also does something called neurofeedback, where he straps sensors on his head that remind him to stay focused on his task.
• He takes Tuesdays off and stays away from the team, which he acknowledged threw his coaches for a loop. On one such Tuesday, he went for a walk with his wife Julie, responded to fan mail, and perused a Barnes & Noble store.
• We knew Kirk was durable — he's never missed a game to injury in his five seasons with the Vikings. But the documentary shows the pain he endures and his toughness. He had taken so many shots to his midsection early in the season last year that he looked miserable during the team's miraculous comeback over the Buffalo Bills.

Nick's thought bubble: The documentary provides an at-times fascinating glimpse behind-the-scenes on how quarterbacks prepare each week.

• But it never delves into some of the tougher topics, like why Cousins and former head coach Mike Zimmer didn't get along. There was no indication he was even asked about that.
