Input: Question: How old was Frank Bush the year he was fired? Passage 1:The first NCAA Tournament was organized by the National Association of Basketball Coaches. Oregon won the inaugural tournament, defeating Ohio State 4633 in the first championship game. Before the 1941 tournament, control of the event was given to the NCAA. In the early years of the tournament, it was considered less important than the National Invitation Tournament (NIT), a New York City-based event. Teams were able to compete in both events in the same year, and three of those that did soUtah in 1944, Kentucky in 1949, and City College of New York (CCNY) in 1950won the NCAA Tournament. The 194950 CCNY team won both tournaments (defeating Bradley in both finals), and is the only college basketball team to accomplish this feat. By the mid-1950s, the NCAA Tournament became the more prestigious of the two events, and in 1971 the NCAA barred universities from playing in other tournaments, such as the NIT, if they were invited to the NCAA Tournament. The 2013 championship won by Louisville was the first men's basketball national title to ever be vacated by the NCAA after the school and its coach at the time, Rick Pitino, were implicated in a 2015 sex scandal involving recruits.
Passage 2:The Texans responded to the 2010 poor defensive showing by firing defensive coordinator Frank Bush, secondary coach David Gibbs, linebackers coach Johnny Holland, and assistant linebackers coach Robert Saleh. Kubiak, a ball boy for beloved former Houston Oilers head coach O.A. "Bum" Phillips in the 1970s, hired long-time friend, and Bum's son, Wade Phillips to take over as the Texans' new defensive coordinator on January 5, 2011. Phillips became available after being fired as head coach of the Dallas Cowboys halfway through the 2010 season. Phillips was allowed to bring in his own assistant coaches. The Texans signed two high-profile free agent defensive backs, Johnathan Joseph and Danieal Manning, and used their first five draft picks, including two in the second round of the 2011 NFL Draft, on more defensive players.
Passage 3:At the time, the term "Southern Syria" referred to a political position which implied support for the Greater Syria nationalism associated with the kingdom promised to the Hashemites of the Hejaz by the British during World War I. After the war, the Hashemite prince Faisal attempted to establish such a Pan-Syrian or pan-Mashriq state (i.e. a united kingdom that would comprise all of modern Syria, as well as Mount Lebanon and Palestine, including Transjordan, so that Palestine would be the province of "Southern Syria"). This kingdom was to be united with the other Hashemite domains in Hejaz and Iraq, thus contributing in large measure towards the fulfillment of Pan-Arabist ambitions. However, he was stymied by conflicting promises made by the British to different parties (see SykesPicot Agreement, Balfour Declaration and McMahonHussein Correspondence), leading to the Franco-Syrian War, which destroyed the Arab Kingdom of Syria in 1920.
