The Player: NFL super agent Drew Rosenhaus

He doesn't put on pads or walk the sidelines, but Drew Rosenhaus may be the most important player in football, or so he thinks. "The NFL would fall apart without me," he says.

Drew Rosenhaus is one of football's most valuable players, but you won't find him on the field. The legendary agent has amassed 170 clients, more than anyone else in the business -- and is widely despised for it by his competition. So how did this real-life Jerry Maguire build his empire? As Scott Pelley reports, Rosenhaus spends his days in a nonstop frenzy, calling and texting teams and players to hash out multi-million dollar deals. That grueling drive cuts into his sleep and his personal life, but Rosenhaus says, "It's kill or be killed in this business. And I intend to do the killing."

The following script is from "The Player" which aired on Oct. 9, 2011.

While NFL players have to be ferocious on the field, off the field, their agents have to be just as tough. Agents go toe-to-toe with the teams, negotiating their players' contracts. And some agents become both brother and father to their clients. The most memorable agent of all time was the movie character, Jerry Maguire. But the stuff that that character was made of was largely based on the super agent Rosenhaus. There are almost a thousand agents in the NFL, but no one represents more players than Rosenhaus. An agent who is at the same time revered, feared and hated. And to hear him tell it, he just may be the most important player in all of pro-football.

Keeping up with NFL super agent Drew Rosenhaus
On this week's "Overtime", watch as our "60 Minutes" team tries to keep up with the man who inspired the film "Jerry Maguire"

Drew Rosenhaus: I really believe that the NFL would fall apart without me. That may sound cocky, that may sound arrogant, but I'm telling you the truth.

Pelley: Cocky and arrogant, you?

So why would the NFL fall apart without Drew Rosenhaus?

Rosenhaus: In the NFL we keep things moving smoothly. When it breaks down between the team and the player, the agent is there to pick up those pieces. If a guy says, 'I wanna be traded; I hate this team, I hate this coach.' I say to the player, 'Tell me, don't tell the coach. I don't want you to ruin your relationship with the team. Come to me."

Pelley: Let me let the audience in on something here. People watching this interview right now are thinking, 'Rosenhaus is turning this on for the camera. He's leaning forward and raising his voice and shouting because he knows he's on TV.' You and I earlier today were in your office and you were shouting at me just this way before the cameras were rolling.

Rosenhaus: Scott, I don't see the shouting.

Pelley: This is the real deal.

Rosenhaus:You know, this is just enthusiasm.

Pelley: This isn't shouting?

Rosenhaus: No, I think I'm just talking to you. I didn't--am I loud?

Pelley: No, I --

Rosenhaus: Sorry guys. Let's turn down the mic.

He doesn't drink coffee. Imagine what he'd be like on caffeine.

[Rosenhaus: "Come on!"]

No alcohol either, but he is a work-aholic.

[Rosenhaus on phone: Real good job today buddy. I guess you're not going to fire me. We'll be able to get you even more money. Try and be available tomorrow. Trust me!]

Rosenhaus: I live it, eat it, sleep it, every single minute of the day I think about my work. I love it. It's my passion. I enjoy it. So it's not like it's a job. It's just--it's fun.

His clients include flamboyant wide receiver Chad Ochocinco; star running back Frank Gore and quarterback Rex Grossman.

[Rosenhaus: Way to go stud, I'm really proud of you.]

And two of the leagues fastest rising future superstars: receiver Rob Gronkowski; and explosive running back Lesean McCoy.

He works out with his players during the day, parties with them at night. And he is always, always on call.

Rosenhaus: If I get a call in the middle of the night, I have to take it. If I'm with a girl I have to take it. If I'm in the shower, I have to take it.

Rosenhaus: My clients are like my family, like my brothers literally. So when they hurt I hurt and there's a lot of emotion involved. You know you enjoy the ups and man do you feel the downs.

Pelley: But come on, you've got how many clients now?

Rosenhaus: Approximately 170 active clients.

Pelley: You can't have a personal relationship with 170 guys.

Rosenhaus: Scott, I do. I want each one of my clients to feel that they are my only client, that they are my most important client, that I love them.
