Background: Frank Joseph Kush (January 20, 1929 - June 22, 2017) was an American football player and coach. He served as the head coach at Arizona State University from 1958 to 1979, compiling a record of 176-54-1. Kush was also the head coach of the Canadian Football League's Hamilton Tiger-Cats in 1981, the National Football League's Baltimore/Indianapolis Colts from 1982 to 1984, and the Arizona Outlaws of the United States Football League in 1985. He was inducted into the College Football Hall of Fame as a coach in 1995.
Context: In September 1979 former Sun Devil punter Kevin Rutledge filed a $1.1 million lawsuit against the school, accusing Kush and his staff of mental and physical harassment that forced him to transfer. The most dramatic charge was that Kush had punched Rutledge in the mouth after a bad punt in the October 28, 1978, game against the Washington Huskies. During the next few weeks, overzealous fans turned things ugly when the insurance office of Rutledge's father suffered a fire and the family's attorney received two death threats.  On October 13, 1979, Kush was fired as head coach for interfering with the school's internal investigation into Rutledge's allegations. Athletic director Fred Miller cited Kush's alleged attempts to pressure players and coaches into keeping quiet. The decision came just three hours before the team's home game against Washington. Kush was allowed to coach the game, with the Sun Devils pulling off an emotional 12-7 upset of the sixth-ranked Huskies, fueled by the angry crowd incensed by the decision. After the game ended, Kush was carried off the field by his team. The win gave him a 3-2 record on the season, but all three victories were later forfeited when it was determined that Arizona State had used ineligible players.  After nearly two years, Kush would be found not liable in the case, but remained absent from the sideline throughout 1980, the first time in more than 30 years that he had been away from the game.  Future NFL players who played under Kush at Arizona State include Charley Taylor, Curley Culp, Danny White, Benny Malone, Mike Haynes, John Jefferson and Steve Holden. Baseball Hall of Famer Reggie Jackson also played a year of football at Arizona State for Kush on a football scholarship before switching to baseball.
Question: Then what happened
Answer: remained absent from the sideline throughout 1980, the first time in more than 30 years that he had been away from the game.

Problem: Background: Richard Milhous Nixon was born on January 9, 1913 in Yorba Linda, California, in a house that was built by his father. His parents were Hannah (Milhous) Nixon and Francis A. Nixon. His mother was a Quaker, and his father converted from Methodism to the Quaker faith. Nixon was a descendant of the early American settler, Thomas Cornell, who was also an ancestor of Ezra Cornell, the founder of Cornell University, as well as of Jimmy Carter and Bill Gates.
Context: Nixon laid the groundwork for his overture to China before he became president, writing in Foreign Affairs a year before his election: "There is no place on this small planet for a billion of its potentially most able people to live in angry isolation." Assisting him in this venture was his National Security Advisor and future Secretary of State, Henry Kissinger, with whom the President worked closely, bypassing Cabinet officials. With relations between the Soviet Union and China at a nadir--border clashes between the two took place during Nixon's first year in office--Nixon sent private word to the Chinese that he desired closer relations. A breakthrough came in early 1971, when Chairman Mao invited a team of American table tennis players to visit China and play against top Chinese players. Nixon followed up by sending Kissinger to China for clandestine meetings with Chinese officials. On July 15, 1971, it was simultaneously announced by Beijing and by Nixon (on television and radio) that the President would visit China the following February. The announcements astounded the world. The secrecy allowed both sets of leaders time to prepare the political climate in their countries for the contact.  In February 1972, Nixon and his wife traveled to China. Kissinger briefed Nixon for over 40 hours in preparation. Upon touching down, the President and First Lady emerged from Air Force One and greeted Chinese Premier Zhou Enlai. Nixon made a point of shaking Zhou's hand, something which then-Secretary of State John Foster Dulles had refused to do in 1954 when the two met in Geneva. Over 100 television journalists accompanied the president. On Nixon's orders, television was strongly favored over printed publications, as Nixon felt that the medium would capture the visit much better than print. It also gave him the opportunity to snub the print journalists he despised.  Nixon and Kissinger met for an hour with Mao and Zhou at Mao's official private residence, where they discussed a range of issues. Mao later told his doctor that he had been impressed by Nixon, whom he considered forthright, unlike the leftists and the Soviets. He said he was suspicious of Kissinger, though the National Security Advisor referred to their meeting as his "encounter with history". A formal banquet welcoming the presidential party was given that evening in the Great Hall of the People. The following day, Nixon met with Zhou; the joint communique following this meeting recognized Taiwan as a part of China, and looked forward to a peaceful solution to the problem of reunification. When not in meetings, Nixon toured architectural wonders including the Forbidden City, Ming Tombs, and the Great Wall. Americans received their first glimpse into Chinese life through the cameras which accompanied Pat Nixon, who toured the city of Beijing and visited communes, schools, factories, and hospitals.  The visit ushered in a new era of Sino-American relations. Fearing the possibility of a Sino-American alliance, the Soviet Union yielded to pressure for detente with the United States.
