When you pick up a newspaper, do you reach first for the sports section? When you sit down in front of a television, do you look first for ESPN or today's hottest game? Does your mood revolve not just around whether the world is better off today but whether the team you root for won or lost?

I love sports. Playing sports, I've probably had more peak moments in which my ego was dissolved and I was able to merge body, mind, and spirit in the pursuit of a goal in full collaboration with others than doing anything else. Sports have always served as a bridge among strangers as well as friends - whether the ability to show up at a basketball court anywhere in the world and join a game within minutes or to strike up a conversation with anyone anywhere regardless of race, class, faith, or nationality. How many fathers and sons have had sports in common when all else seems strained or broken between them?

All of which has a streak of purity about it. But what about professional sports? This week's guest DAVE ZIRIN fills a fairly unique role in our culture. He takes sports seriously enough to be the first sports editor in the 150 year existence of The Nation magazine. He has for years in books, columns, and commentaries examined both the politics of sports as well as the intersection of the two.

Howard Cosell said "rule number one of the jockocracy" was that sports and politics don't mix. In his newest book, Game Over, Zirin asserts that modern professional athletes are breaking that rule like never before. From the NFL lockout and the role of soccer in the Arab Spring to the Penn State sexual abuse scandals and Tim Tebow's on-field genuflections, Dave reveals how our most important debates about class, race, religion, sex, and political power are being played out both on and off the field.

I've left my overzealous interest in sports out of the studio for years, but this week -- a couple of weeks after the Super Bowl, not long after Lance Armstrong finally admits to doping, and a few hours before the NBA All Star game - I break that barrier. Dave Zirin and I will talk about specific events and athletes, but we'll also examine the role sports plays in our individual lives and in society.
