Context paragraphs:
NCAA Division III women's ice hockey: As of the 2011-2012 season, there were 49 teams competing in NCAA Division III women’s hockey in five conferences.  In addition, there were three colleges who are not in Division III who compete primarily against Division 3 schools (and participate in a Division III conference), bringing the total number of teams competing in regular season play to 52 schools (there is one Division 1 team, and two Division 2 teams who play predominantly Division 3 schedules).  Many NCAA Division III schools are smaller than NCAA Division 1 colleges, though size is not the determining factor.  There is a mix of private colleges and public colleges (and universities) among the NCAA Division III schools.  Some women student-athletes play two sports in NCAA Division III, though it remains a challenge to mix hockey and another sport because as a winter sport, hockey will still overlap with a fall or spring sport.

Kansas Jayhawks: The Kansas Jayhawks, commonly referred to as KU or Kansas, are the athletic teams that represent the University of Kansas.  KU is one of three schools in the state of Kansas that participate in NCAA Division I.  The Jayhawks are also a member of the Big 12 Conference.  KU athletic teams have won thirteen NCAA Division I championships: five in men's basketball, one in men's cross country, three in men's indoor track and field, three in men's outdoor track and field, and one in women's outdoor track and field.

Flex offense: The Flex offense is an offensive strategy in basketball developed in the 1970s.  It is a patterned offense relying on cuts across the key (called a "flex cut") and down screens to create a "pick-the-picker" action.  This offense is most effective against a man-to-man defense, though some ambitious coaches have used it against odd front zones.  It is the favored offense of many high school programs because it requires players to be in constant motion and the patterns of screens and cuts are easy to remember.  Though dismissed by many coaches at the college level for its predictability, some notable programs still rely on it.  It has been run by many NCAA teams, including by Gary Williams of the University of Maryland.  Williams used the flex offense to lead the Terrapins to the 2002 NCAA National Championship.  Also, Gordie James of Willamette University used the flex offense to lead the Bearcats to the 1993 NAIA Division II National Championship.  Additionally, Jerry Sloan ran his variation of it for years with the Utah Jazz.

2016 NCAA Division I Cross Country Championships: The 2016 NCAA Division I Cross Country Championships were the 78th NCAA Men's Division I Cross Country Championship and the 36th NCAA Women's Division I Cross Country Championship to determine the national champions of men's and women's NCAA Division I collegiate cross country running.  They were hosted by Indiana State University at the LaVern Gibson Cross Country Course in Terre Haute, Indiana on November 19, 2016.  Four different championships will be contested: men's and women's individual and team championships.

Centennial Jay: Centennial Jay, or C Jay for short, was one of the costume mascots of the University of Kansas.  He with fellow mascot Big Jay and Baby Jay are Jayhawks.  C Jay was created by student cartoonist Henry Maloy and featured in the University Daily Kansan in 1912.  Maloy's depiction of the Jayhawk helped answer the question of what the mythical bird would look like.  When asked why he gave the bird shoes Maloy responded, "Why?  For kicking opponents, of course."  C Jay was reintroduced as a full-sized mascot on February 25, 2012 in the final Border War against Missouri to celebrate the 100th anniversary of the Jayhawk.  C Jay was retired early in 2013 and is displayed in Allen Fieldhouse.

Rice–Totten Stadium: Rice–Totten Stadium is a 10,000-seat multi-purpose stadium in Itta Bena, Mississippi, United States.  It is home to the Mississippi Valley State University Delta Devils college football team.  The stadium is named after former MVSU football players Jerry Rice and Willie Totten who set many NCAA Division I-AA records in the 1980s.  Rice went on to become an NFL legend and Pro Football Hall of Fame inductee.  Totten played professional football after college and then went into coaching, including serving as the head coach for MVSU.  He is one of the few college football coaches to have coached a game at a facility named after themselves.

2015 NCAA Division I Cross Country Championships: The 2015 NCAA Division I Cross Country Championships were the 77th NCAA Men's Division I Cross Country Championship and the 35th NCAA Women's Division I Cross Country Championship to determine the national champions of men's and women's NCAA Division I collegiate cross country running.
