Context paragraphs:
2010–13 Atlantic 10 Conference realignment: The 2010–13 Atlantic 10 Conference realignment refers to the Atlantic 10 Conference dealing with several proposed and actual conference expansion and reduction plans among various NCAA conferences and institutions from 2010 to 2013.  Moves that involved the Atlantic 10 Conference were part of a much larger NCAA conference realignment.

2010–13 Western Athletic Conference realignment: The 2010–13 Western Athletic Conference realignment refers to the Western Athletic Conference (WAC) dealing with several proposed and actual conference expansion and reduction plans among various NCAA conferences and institutions from 2010 to 2013.  Moves involving the WAC were a significant part of a much larger NCAA conference realignment in which it was one of the most impacted conferences.  Of the nine members of the WAC in 2010, only two—the University of Idaho and New Mexico State University—remained in the conference beyond the 2012–13 school year, and Idaho departed for the Big Sky Conference after the 2013–14 school year.  Five pre-2010 members are now all-sports members of the Mountain West Conference (MW), and another joined the MW for football only while placing most of its other sports in the Big West Conference.  Another pre-2010 member joined Conference USA (C-USA) in July 2013.

Eagle (British comics): Eagle was a seminal British children's comics periodical, first published from 1950 to 1969, and then in a relaunched format from 1982 to 1994.  It was founded by Marcus Morris, an Anglican vicar from Lancashire.  Morris edited a Southport parish magazine called "The Anvil", but felt that the church was not communicating its message effectively.  Simultaneously disillusioned with contemporary children's literature, he and "Anvil" artist Frank Hampson created a dummy comic based on Christian values.  Morris solicited the idea to several Fleet Street publishers, with little success, until Hulton Press took it on.

Kansas Jayhawks men's basketball: The Kansas Jayhawks men's basketball program is the intercollegiate men's basketball program of the University of Kansas.  It is one of the oldest and is one of the most successful programs in the history of basketball.  The program is classified in the NCAA's Division I and the team competes in the Big 12 Conference.

2010–13 Big East Conference realignment: The 2010–13 Big East Conference realignment refers to the Big East Conference dealing with several proposed and actual conference expansion and reduction plans among various NCAA conferences and institutions.  Following on the 2005 NCAA conference realignment, resulting in the move of 23 teams across various conferences after an initial raid of three Big East teams, the Big East was severely impacted in the follow-up 2010–2014 NCAA conference realignment.  Beginning in the 2010-11 academic year and continuing into 2013, 13 Big East schools announced their departure for other conferences and 13 other schools announced plans to join the conference (eight as all-sports members, and five for football only), but three of the latter group later backed out of their plans to join (one for all sports, and the other two for football only).  Most notably, the seven schools that did not sponsor football in Division I FBS announced in December 2012 that they would leave as a group, which led to a formal split of the conference effective in July 2013.

ECAC Lacrosse League: The ECAC Lacrosse League was an American NCAA Division I college athletic conference and part of the Eastern College Athletic Conference.  Founded in 1999 with play beginning in 2000, this part of the conference only sponsored men's lacrosse.  It disbanded at the end of the 2014 season as an indirect result of the early-2010s NCAA conference realignment.

Marcus Morris (basketball): Marcus David Morris (born September 2, 1989) is an American professional basketball player for the Boston Celtics of the National Basketball Association (NBA).  The 6'9" forward played college basketball at Kansas before being drafted 14th overall by the Houston Rockets in the 2011 NBA draft.

BYU Cougars: The BYU Cougars are the intercollegiate athletic teams that represent Brigham Young University (BYU), a major university located in Provo, Utah.  BYU fields 21 National Collegiate Athletic Association (NCAA) varsity athletic teams.  They are a member of the West Coast Conference for most sports.  Other sports compete in the Mountain Pacific Sports Federation and as independents.  They were a member of the Mountain West Conference (MW) from its formation in 1999 until leaving in 2011 as part of a major NCAA conference realignment.  Before the formation of the MW, the Cougars competed in the Rocky Mountain Athletic Conference, the Mountain States Conference, and the Western Athletic Conference.

2010–12 Southeastern Conference realignment: The 2010–12 Southeastern Conference realignment refers to the Southeastern Conference (SEC) dealing with several proposed and actual conference expansion and reduction plans among various NCAA conferences and institutions.  Moves that involved the SEC were a relatively small part of a much larger NCAA conference realignment that began in the 2010-11 academic year and continued through the first half of 2014.  The SEC was one of the least impacted conferences, as no member schools announced plans to join other conferences, while two schools from the Big 12 Conference joined the conference as all-sports members.  Several other schools have been rumored as potential expansion candidates.

2013–14 Phoenix Suns season: The 2013–14 NBA season was the Phoenix Suns' 46th season in the NBA.  This season marked the first time that purple was not a primary color for the team (although it was still involved with their system).  It was also the first time since the beginning of the 1987–88 NBA season that the Suns ended up drafting in the top 5 of a draft.  In addition, it was the first time since the beginning of the 2000–01 NBA season that the Suns made complete changes in not only their logos, but also their jerseys.  When the Suns began the regular season, Goran Dragić, P. J. Tucker, Markieff Morris, and his twin brother Marcus Morris were the only players returning from playing with last season's team (while Channing Frye was still on last season's team, he didn't play any games due to a life-threatening heart ailment he had at the time).  The Phoenix Suns, despite their winning record, failed to make the playoffs.  This drew criticism from many fans regarding the conference system as multiple sub-.500 teams in the Eastern Conference managed to make playoffs, with the Suns holding a Top 4 Eastern Conference seeded team had they been a part of that conference that year instead.
