Later, Tazz was placed into contention for the Intercontinental Championship, but never won the title. In the summer, after taking time off for an arm injury, he was turned into a villainous character and placed into a feud with color commentator Jerry "The King" Lawler. The feud included matches at SummerSlam and Unforgiven, which they split. Tazz was only able to pick up the Unforgiven win when he received help from Raven, who had returned to the company. Afterwards, the duo formed a tag team that lasted until November.
When the Invasion angle began, Tazz acted as "the voice of the Alliance", sticking up for them and speaking on their behalf whenever possible. He eventually left the stable after the leader Stone Cold Steve Austin criticized his decision to stay on commentary rather than help Stephanie McMahon.
Lawler returned to the company on November 19, 2001 and resumed his place as commentator, with Tazz becoming both a wrestler and a commentator. In January he and Spike Dudley won the WWF Tag Team Championship, holding it for over a month before losing it to Billy and Chuck.
With injuries mounting, Tazz began performing part-time commentary on Sunday Night Heat in October 2000. He joined the SmackDown! team in February 2001 after Jerry "The King" Lawler quit the company, after calling his first PPV on No Way Out with Jim Ross, as well as becoming one of the trainers for the WWF produced reality series Tough Enough.
When World Wrestling Entertainment split into two brands, Tazz was put on SmackDown!, where he again became a color commentator. Not long after he retired from the ring, he became a full-time broadcaster. He co-hosted SmackDown! for World Wrestling Entertainment until a third brand, ECW, was introduced in 2006, at which point he became the color commentator for that show.
On June 11, 2006, Tazz wrestled his final match to date, defeating Jerry Lawler at ECW One Night Stand.
During the recording of the April 29, 2008 episode of ECW, Tazz's broadcast partner Mike Adamle abruptly walked off set prior to the main event. Moments later, after reading the promo for the upcoming pay-per-view, Tazz walked out as well, leaving the main event with no commentators.
In August 2008, Tazz filled in for Mick Foley as a color commentator on the SmackDown brand, while Raw wrestler Matt Striker filled in for Tazz on the ECW brand. When Foley left the company, Tazz became the permanent color commentator for the SmackDown brand once again.
On April 3, 2009, Tazz left WWE when his contract expired.
