While Andrea Kremer didn’t necessarily wish for a player to tear an ACL, she threw out an idea last fall.

“I said, ‘What if an Adrian Peterson-type player gets injured like that? Why not follow him around during (his rehabilitation),” Kremer said. “Everyone looked at me like I had four heads. ‘Yeah, right.'”

Shortly thereafter, Kremer had her AP-type player when Darrelle Revis blew out his knee during week 3. Kremer, who covers health issues for the NFL Network, jumped into action, chronicling Revis’ difficult rehab and off-season saga, which saw him leaving the Jets and signing with Tampa Bay.

The end result is Darrelle Revis: A Football Life (9 p.m. ET, tonight, NFL Network). It is a deep inside look at what happens when a superstar’s career gets turned upside down and how he copes with adversity.

Kremer said it was an extraordinary journey for her and the production team. And it almost didn’t happen.

“Darrelle is a very private person,” Kremer said. “This is not his thing at all. We reached out to (his representatives) and said, ‘We have to do this all out. We have to be there before the surgery, during the surgery, and then right after that.’ They agreed to do it.”

Kremer said the day of the surgery stood out in particular for her.

“Here was this multi-million dollar athlete, an All-Pro,” Kremer said. “Yet in the hospital, he’s just like any other patient. The vulnerability factor stood out to me. You’re seeing him at his most vulnerable.”

Kremer said the production team had around 15 shoots with Revis during nearly a year of following him. She said the toughest was Revis’ first game back, which just happened to be at the Jets. Naturally, he was extremely nervous before the game.

However, Revis’ mother, Diana Askew, might have provided the most memorable clip from that day.

“She has a big personality,” Kremer said. “We were sitting with the family in a box, and she yells, ‘Go Jets.’ When we showed the video to Darrelle, he said, ‘What did she say?'”

Kremer said her biggest takeaway from the documentary was the vulnerability and uncertainty these athletes face when they are suddenly thrust into these situations.

“When it all is said and done, they are human,” Kremer said. “They have to deal with all the different things we do. It’s just under a bigger microscope.”
