Peters and his assistant were allowed on the floor. Károlyi obtained a maintenance man's pass so he could be near Retton and McNamara during the competition. ABC television network commented on this controversy during its broadcasts and often showed Mary Lou Retton and Julianne McNamara running over to the stands to speak to Károlyi. During the 1984 Olympics, Károlyi did not have an official position with the delegation. He slept in his car, and ignored Peters' instructions by holding supplementary workouts for his gymnasts. Károlyi's clout in the United States increased after the victories of his students in 1984, but so did resentment against him. After Retton's success in 1984, Károlyi purchased the Karolyi Ranch. He was paid by McDonald's to have their golden arch logo as part of his sleeve design. His new gym, run from the ranch, attracted many of the country's top gymnasts. Following the 1984 Olympics, USGF decided to replace Peters with Greg Marsden as Olympic coach. Marsden was a college coach with no private students and no financial interest in promoting one gymnast at the expense of another. Marsden said that he "thought some of the concerns the other coaches had about Károlyi were legitimate," and selected Donna Cozzo as assistant national coach. Károlyi was furious and had to be dissuaded from boycotting the 1987 Pan American Games. Károlyi did not attend the meet, complaining that he was not allowed to coach although he was "providing fifty percent of the team". Károlyi's star gymnast Kristie Phillips competed in the meet, finishing second behind Sabrina Mar, who trained with former Olympic coach Don Peters at SCATS gym. The United States did not do well in the 1987 World Championships, finishing 6th. Marsden resigned from his position as national team coach in November 1987. After Marsden resigned, Károlyi lobbied to be appointed as national coach, but he was opposed by the other coaches. Don Peters was restored to the position in January 1988. Peters chose Béla's wife Márta Károlyi to serve as assistant national coach. Károlyi told USGF that he would not attend the 1988 Seoul Olympic Games, unless he was the team coach. At the 1988 Olympic Trials in August, Károlyi's gymnasts earned 5 of the top 8 spots. These five gymnasts were Phoebe Mills, Brandy Johnson, Chelle Stack, and the two team alternates Rhonda Faehn and Kristie Phillips. Phillips, who had left Károlyi's gym and
