Your Dark Companion Podcast

What does the business side of sports really look like when you’re in the room where it happens?

In this episode of Your Dark Companion, Mike Rhyner and the crew sit down with longtime sports executive George Killebrew, a key figure behind the scenes of some of the biggest moments in Dallas sports.

Killebrew’s career spans decades — from working at SMU during the infamous “death penalty” era, to helping build the Dallas Mavericks into a top-tier NBA business alongside Mark Cuban, to serving as commissioner of Major League Rugby, and now helping lead the explosive growth of professional pickleball.

Along the way, he shares stories you don’t usually hear:

What it was like selling tickets when SMU football was at rock bottom
How the American Airlines Center came together and changed Dallas sports forever
The reality of working with high-level owners like Mark Cuban, Ross Perot Jr., and Tom Dundon
Why attention to detail (even a spilled drink in section 115) can define a franchise
And how pickleball became one of the fastest-growing sports in America

This episode pulls back the curtain on the decisions, risks, and personalities that shape the sports world — and shows why the business side might be just as fascinating as the games themselves.

If you love sports, business, Dallas history, or behind-the-scenes stories, this is one of those conversations you don’t want to miss.

Mike Rhyner
Mike Rhyner… "a little on the bumpy side, but rather likable"…so stated famously by a grade school teacher in Oak Cliff, where Mike grew up. A complicated guy, yet a guy who can do long division and remember call strike three to A Rod. Probably best left unattended. Don't expect assistance from him if a medical situation arises.

What is Your Dark Companion Podcast?

"Whatever I want it to be about on a given day; is what it is." Your Dark Companion couples your familiar friends from radio, Mike and Grubes! Mike brings his classic interviews that draw you in, and Grubes—The Devil—drops…well the drops, and throws the occasional grenade. Mike likes to draw on his fascinating acquaintances and friends allowing them to tell their stories as you've never heard them. But he also goes outside his network, sharing Grubes' network, and often outside of both, to bring you those they don't know, but believe have a story that will make you laugh, make you think, think differently, or just entertain you…"that's what we are trying to do here."
