Championship across the WWF territory in 1980, earning two-or-three main event matches in most markets. Slaughter was the only WWF-based challenger not to do the honors for Backlund at MSG (Backlund defeated him at the Meadowlands, but never in the Garden). Slaughter then engaged in a feud with Pat Patterson, which stemmed from Slaughter calling Patterson "yellow" and offering him $10,000 (double the usual amount) to try to break the cobra clutch. Patterson accepted on television and was escaping from the hold when Slaughter released it and put a beat-down on Patterson, starting a hot feud which culminated in an "Alley Fight" in New York, New York's Madison Square Garden between the two that is widely regarded as the best "hardcore" match of the Kayfabe era. National Wrestling Alliance (1981–1983) In September 1981, Slaughter joined the National Wrestling Alliance, mainly wrestling for its flagship territory Jim Crockett Promotions. In October 1981, he took part in a tournament to determine a new NWA United States Heavyweight Champion; he defeated Johnny Weaver, Jay Youngblood, and Rick Steamboat in the tournament to win the vacant title. He would hold onto the title for over seven months, before losing the title to Wahoo McDaniel in May 1982. In September 1982, Slaughter and partner Don Kernodle were awarded the NWA World Tag Team Championship, claiming a title victory over Antonio Inoki and Giant Baba in Tokyo. They would be in a heated rivalry with the team of Rick Steamboat and Jay Youngblood, which culminated on March 12, 1983, losing the titles to Steamboat and Youngblood in a steel cage match in Greensboro, North Carolina. After the rivalry ended, Slaughter left JCP. During this period, Slaughter also toured Germany and Austria for the Catch Wrestling Association, twice (in 1982 and 1983) unsuccessfully challenging CWA World Heavyweight Champion Otto Wanz. First return to the WWF (1983–1984) Slaughter returned to the WWF in March 1983, and again took on the Grand Wizard as his manager. He immediately targeted Backlund, who was still the reigning WWF World Heavyweight Champion. Slaughter turned up the feud another notch when he attacked Backlund at a television taping; Backlund was in the process of completing the Harvard step test before Slaughter beat him repeatedly with his riding crop, leaving bruises on his back. Although he won several matches by disqualification, Slaughter was never able to win the title from Backlund. In early 1984,
