After Greg initially captured the title from Wahoo in June; McDaniel took it back in August.  This set up what has been described as one of the best angles in Mid Atlantic history, if not all of pro wrestling.  During a televised match, Valentine applied a hold that apparently broke Wahoo’s leg!  The match was halted, and Greg awarded the decision and the title.  The next week, Valentine came out and berated the Indian star as Wahoo was confined to a wheelchair.  In the next few weeks, Greg showed up on television wearing the famous “I BROKE WAHOO’S LEG” t-shirt, further adding fuel to the fire that already burned inside of Wahoo.  McDaniel returned to action in November of 1977 to settle the score. 

After being stripped of the World Tag titles in April 1978 for what NWA President Eddie Graham deemed as “unprofessional conduct”, Greg teamed with Baron Von Raschke to win back the belts in July.  The unlikely duo of Valentine & Raschke beat Paul Jones & Ricky Steamboat who had won the titles in a tournament.  The newly crowned champs would hold the belts until late 1978.  After losing them to Jimmy Snuka and Paul Orndorff, Greg would move out of the area and head to New York to compete in the WWWF.  He would return to the Mid Atlantic region in 1980. 

During the next few years, Greg seemed to have “dual citizenship” in the NWA (JCP region) and the WW(W)F.  He would wrestle in both organizations and continuing his winning ways.  Greg would capture the U.S. title in 1980 after splitting with Flair in another classic televised match.  Valentine turned heel on Flair and actually busted Flair’s nose in the process!  Ric, who was the US Champ at the time, put the belt on the line against his former partner.  Greg came out victorious and won the title.  Valentine also enjoyed another reign as NWA WTT champion, this time with the veteran Ray “The Crippler” Stevens.  Then, after being involved in a short program with Sweet Ebony Diamond (Rocky Johnson) and trading the Mid Atlantic Television title for a few months, Greg returned to the WWF.  He would once again come back to JCP in 1982. 

During what turned out to be his final push in the area, Greg was once again wearing the United States Heavyweight Championship.  He won the title from a familiar face…Wahoo McDaniel in November of 1982 in Norfolk, Virginia.  However, the next year (1983) would see Greg reach a new level of brutality as he battled “Rowdy” Roddy Piper.  Their feud reached such heights (or depths, depending on your perspective), these two had to face each other in a “Dog Collar” match at the first Starrcade.  This match saw Piper come out the winner, but Valentine made him pay for it by severely injuring Roddy’s ear and “hanging” Piper from the ropes using the chain attached to the dog collars.
