Receiver follows five players during the 2023 season, in which Jefferson missed two months with a hamstring injury.

He was unable to complete his first game back as he suffered a tackle to the ribs that left him spitting blood.

While he was on the sidelines, the series shows Jefferson offering advice and encouragement to rookie receiver Jordan Addison. Moments later Addison scores a touchdown.

The 22-year-old told BBC Sport that Jefferson tells him to “be yourself, be creative”.

“He’s an amazing person,” Addison added. “He’s a really humble superstar, who just loves to see everybody [on the team] succeed.”

McCardell said: “Justin’s a superstar that works extremely hard. When Jordan and everybody else sees that, they know they’ve got to work that hard to catch up.”

That work ethic extends to a quest for perfection, which Jefferson shows in Receiver when agonising over a crucial fumble. He’s continued to show it in the off-season.

“He sent me a video earlier this year, before we came back for mini-camp,” said McCardell. “I said ‘I see you working on your body posture and your break, you’re getting your shoulders down now’. And he said ‘yeah, you told me to’.

“It’s simple stuff like that. I tell him, and he goes and works on his whole game. He wants to be as perfect as a receiver can be. It’s a great honour for me that he believes in what I teach and he’s out there working on it.”
