Williams first became popular as 'The Hammer', Mike Rhyner's partner on KTCK's top-rated The Hardline drivetime show, but his tenure there ended abruptly in 2008 after 13 years on the air.
[2] It was also in the early 1990s that he first partnered with Mike Rhyner, with whom "Greggo" would become well known in the DFW area as co-host of the local hit radio show The Hardline.
Rhyner, once "sports guy" on KZEW's much-lauded The Morning Zoo with LaBella & Rody, launched all-sports station KTCK in 1994, taking Williams with him to co-anchor the all-important drivetime slot.
Greggo was recognized as a top ten radio sports personality in the Nation, and the Hardline was constantly #1 in Arbitron ratings Men 25-54 demographic.
[1] On December 20, KTCK was sent a "Cease and Desist" letter from Williams' attorneys preventing the station from referencing the former co-worker in any way by name or by on-air drops.
[5] A few months later, in a cover story in the Dallas Observer, Williams described the entire series of events, admitting to cocaine abuse and other difficulties.
[7][8] It was eventually confirmed by Dallas Observer staff writer Richie Whitt that Williams was officially no longer working at ESPN Radio.
[9] However, Williams stated the actual reason he resigned from ESPN was due to station management refusing him to use the on air antics that he had found much success with on KTCK.
[16][17] On December 6, 2022, Williams reunited with Mike Rhyner, who had retired in 2019 but returned to host an afternoon drivetime radio show at 97.1 The FREAK, now KEGL.
The pair discussed Williams' drug issues and how he was fired from KTCK and reminisced about the good times as the top rated talk show hosts.
