Pit Bull was a debate show that aired live every Saturday on Speed during the 2004 NASCAR season. The show took place outside of every venue of the NASCAR Cup Series. Host Steve Byrnes moderated debates involving a four-person panel of sportswriters whose columns are mostly about racing. The three primary panelists were Mike Mulhern of the Winston-Salem Journal, David Poole of The Charlotte Observer, and Marty Smith of NASCAR.com. The fourth panelist usually rotated between writers like Ben Blake, Lee Spencer of The Sporting News, and Speed Channel website writer Robin Miller. The panelists eventually became known as the "Pit Hogs."
