イワン・プトスキー
On October 2, 1972, Graham premiered in Verne Gagne's American Wrestling Association (AWA) based in Minneapolis, where he took on the moniker "Superstar". As he toured the north-central states and adjacent areas of Canada, Graham feuded with Gagne, The Crusher, The Bruiser, Wahoo McDaniel, Billy Robinson, Ken Patera and Ivan Koloff, the latter becoming his tag-team partner. By this time, Graham was integrating into his performances not only arm wrestling contests but also weightlifting challenges (mainly involving ex-Olympian Ken Patera) and posing routines. One of his most memorable feuds was against McDaniel, with whom he wrestled numerous bouts with between 1973 and 1974. Among the matches they participated in were Indian Strap matches. It was during the feud with McDaniel that Superstar also teamed with Koloff to take on McDaniel and The Crusher in tag team matches. It was also during his time in the AWA that he began wrestling Ivan Putski.
