Tuesday night’s edition of Real Sports with Bryant Gumbel (HBO, 9 p.m.) looks at the insanely driven Jon Gruden.

At age 49, Gruden has been out of coaching since 2008. He is about to begin his fourth season on ESPN’s Monday Night Football.

It still seems that it is just a matter of time before he returns to the sidelines. But then again, that’s what we were saying in 2009.

Here’s this exchange on the show.

BRYANT GUMBEL:  You’ve had a bunch of job offers.

JON GRUDEN: Yeah, I’ve had opportunities to come back.

BRYANT GUMBEL: Pro?

JON GRUDEN: Pro.

BRYANT GUMBEL: College?

JON GRUDEN: College.

BRYANT GUMBEL: What’s stopping you?

JON GRUDEN: I don’t know. I’m tryin’ to figure out– I’m tryin’ to figure out where I’m goin’. If the right opportunity presents itself, I will come back.

Here’s another segment in which Gruden talks about his lifestyle, if you could call it that.

JON GRUDEN: Who needs sleep? You know, who needs it?

BRYANT GUMBEL: You- drive yourself hard.

JON GRUDEN:  Yeah.  If you’d call it that.  You know–

BRYANT GUMBEL: What should I call it?  I mean, a guy who gets up at 3:15, that’s– that’s– that’s drivin’ pretty hard, Jon.

JON GRUDEN: Yeah, it’s–probably not wise at times, probably not normal .  It’s my rhythm. It’s the beat that I go to.
