Context paragraphs:
Billy Preston (basketball): Billy Preston (born October 26, 1997) is an American college basketball player for the Kansas Jayhawks.

Magnus Mainland: Magnus Mainland (1878 – September 4, 1959) was a college football lineman and college basketball player and founding coach for The University of Texas at Austin.  Mainland was a native of Scotland.  Mainland was a nationally known basketball player as an undergraduate student at Wheaton College (Illinois).  His Wheaton team was able to compete in the college basketball competition in the 1904 Summer Olympics in St. Louis, the first Olympic Games featuring the young sport (although only as a demonstration sport).  Wheaton placed second out of the three competing college basketball teams.  Following his graduation from Wheaton, Mainland enrolled in engineering courses at The University of Texas.  While a student there, he was able to convince University officials to permit him to organize, coach, and play on the University's first varsity basketball team.  The Longhorns took the court for the first time on March 10, 1906, defeating the Baylor Bears 27–17 at outdoor Clark Field.  Texas won seven of the eight games scheduled in its inaugural season.  Mainland's second and final season as head coach resulted in a 4–4 overall record.  Due to inadequate funding, the University Athletics Council canceled the basketball program after two seasons, leaving Texas without a basketball team for 1908.  The program was reinstated in 1909 under the direction of UT German studies faculty member and previous Longhorn football head coach (1907–08) W. E. Metzenthin, who had supported students in their efforts to have the program revived.

Penn–Princeton basketball rivalry: The Penn–Princeton basketball rivalry is an American college basketball rivalry between the Penn Quakers men's basketball team of the University of Pennsylvania and Princeton Tigers men's basketball team of Princeton University.  Having been contested every year since 1903, it is the third oldest consecutively played rivalry in National Collegiate Athletic Association Division I history.  Unlike many notable college basketball rivalries, such as Carolina–Duke, which involves teams that often both get invited to the same NCAA tournaments, Notre Dame–UCLA, which involves geographically remote teams, Illinois–Missouri, which involves non-conference rivals, or Alabama–Auburn, which takes a back seat to the football rivalry, this is a rivalry of geographically close, conference rivals, who compete for a single NCAA invitation and consider the basketball rivalry more important than other sports rivalries between the schools.  A head-to-head contest has been the final regularly scheduled game of the Princeton season every year since 1995.  Between 1963 and 2007, Princeton or Penn won or shared the Ivy League conference championship every season except 1986 and 1988.  The other seasons in which neither team won or shared the Ivy League title are 1957, 1958, 1962, 2008–10, and 2012-2016.

Gonzaga–Saint Mary's men's basketball rivalry: The Gonzaga–Saint Mary's men's basketball rivalry is an intra-West Coast Conference college basketball rivalry between the Saint Mary's Gaels men's basketball team of Saint Mary's College of California in Moraga, California and the Gonzaga Bulldogs men's basketball team of Gonzaga University in Spokane, Washington.  Many analysts and members of the media have touted the Gaels vs. Zags as one of the best, if not the best, college basketball rivalry on the West Coast, as both teams have been consistently two of the top three teams in the conference over the last 2 decades.  Gonzaga and Saint Mary's have combined to win 19 out of the last 23 conference championship games, including 17 of the last 19 and each of the last nine.  The two teams have met a total of 96 times dating back to 1955 and currently meet biannually as a part of WCC conference play, with the potential to play a third game in the WCC Tournament and a fourth in the postseason.  As of March 2017, they have met 16 times in the WCC Tournament but have never met in any postseason tournaments beyond the end of conference play.

1995–96 Princeton Tigers men's basketball team: The 1995–96 Princeton Tigers men's basketball team represented Princeton University in intercollegiate college basketball during the 1995–96 NCAA Division I men's basketball season.

The team was the champion of the Ivy League, which earned them an invitation to the 64-team 1996 NCAA Men's Division I Basketball Tournament where they were seeded thirteenth in the Southeast Region.  This was the final year that Carril coached the men's basketball team.  He would be succeeded by assistant coach Bill Carmody.  Carrill retired as the Ivy League's winningest coach in terms of overall victories, conference victories and conference championships.  By the end of the decade, Princeton achieved a 76.1% (210–66) winning percentage, which was the eighth best in the nation.

Kansas Jayhawks men's basketball: The Kansas Jayhawks men's basketball program is the intercollegiate men's basketball program of the University of Kansas.

The team was led by All-American Mike McGee.  The team set the current Big Ten conference record by playing in six overtime games.  That season McGee also set the current conference record for career field goals attempted (2077).
