Context paragraphs:
2001–02 Georgetown Hoyas men's basketball team: The 2001–02 Georgetown Hoyas men's basketball team represented Georgetown University in the 2001–2002 NCAA Division I basketball season.  The Hoyas were coached by Craig Esherick and played most of their home games at the MCI Center in Washington, DC, although they played some home games early in the season at McDonough Gymnasium on the Georgetown campus.  The Hoyas were members of the West Division of the Big East Conference.  They finished the season 19-11, 9-7 in Big East play.  They advanced to the quarterfinals of the 2002 Big East Men's Basketball Tournament before losing to Miami in overtime.  Missing an at-large bid to the 2002 NCAA Men's Division I Basketball Tournament, Georgetown instead received an invitation to play in the 2002 National Invitation Tournament (NIT), but declined it and had no postseason play, the first Georgetown men's basketball team since the 1973-74 season to appear in neither the NCAA Tournament or the NIT.

Hamilton Nationals: The Hamilton Nationals were a Major League Lacrosse (MLL) professional men's field lacrosse team based in Hamilton, Ontario, Canada.  They began play in the 2009 season in Toronto, Ontario as the Toronto Nationals, becoming the first-ever Canadian team in MLL history.  In 2009, they played their home games at BMO Field, which is also home to Major League Soccer's Toronto FC but moved to the smaller Lamport Stadium for the 2010 season.  On February 3, 2011, the Nationals announced that they were relocating to Hamilton, Ontario, and would play their home games at Ron Joyce Stadium on the campus of McMaster University.  On 21 November 2013, MLL announced that the team would not participate in the 2014 season, with most of the players being transferred to the expansion Florida Launch.

Portland Trail Blazers all-time roster: The Portland Trail Blazers, commonly known as the Blazers, are an American professional basketball team based in Portland, Oregon.  They play in the Northwest Division of the Western Conference in the National Basketball Association (NBA).  The Trail Blazers originally played their home games in the Memorial Coliseum, before moving to the Rose Garden in 1995.  The franchise entered the league in 1970, and Portland has been its only home city.  The franchise has enjoyed a strong following; from 1977 through 1995, the team sold out 814 consecutive home games, the longest such streak in American major professional sports.  The Trail Blazers are the only team in the major professional North American sports leagues located in the state of Oregon.  The Trail Blazers are also currently the only NBA team based in the binational Pacific Northwest, after the Vancouver Grizzlies relocated to Memphis and became the Memphis Grizzlies in 2001, and the Seattle SuperSonics relocated to Oklahoma City and became the Oklahoma City Thunder in 2008.

List of Green Bay Packers stadiums: The Green Bay Packers have played home games in eight stadiums since their establishment as a professional football team in 1919.  Their first home was Hagemeister Park, where they played from 1919 to 1922, including their first two seasons in the National Football League (NFL).  Hagemeister Park was a park owned by the Hagemeister brewery; during games ropes were set-up around the field and attendees either walked up or parked their cars nearby and used them for seats.  After the first season, a small grandstand was built and the field was fenced off.  Green Bay East High School was built at the location of Hagemeister Park in 1922, which forced the Packers to move to Bellevue Park, a small minor league baseball stadium that seated 5,000.  They only played for two seasons at Bellevue Park before moving to City Stadium in 1925.  Although City Stadium was the Packers' official home field, in 1933 they began to play part of their home schedule in Milwaukee to attract more fans and revenue.  After hosting one game at Borchert Field in 1933, the Packers played two or three home games each year in Milwaukee, at Wisconsin State Fair Park from 1934 to 1951 and at Marquette Stadium in 1952.  The games were moved to Milwaukee County Stadium after it opened in 1953 and continued through 1994, after which the Packers moved back to Green Bay permanently.

Hartford Colonials: The Hartford Colonials, originally the New York Sentinels, were a professional American football team that played in the United Football League in its 2009 and 2010 seasons.  A charter member of the UFL, the Sentinels began play in 2009 nominally representing New York City but playing its home games in three stadiums, none of which were in the city proper: Rentschler Field in East Hartford, Connecticut; Shuart Stadium in Hempstead, New York (on Long Island); and the now-demolished Giants Stadium in East Rutherford, New Jersey.  (The Sentinels had scheduled a game for Citi Field in Queens but relocated that game to Long Island.)  As the Colonials, the team played all of its home games at Rentschler Field in East Hartford, representing the adjacent city of Hartford.  League-wide financial problems and the high rate of rent at "The Rent" led to the league suspending the Colonials' operations in August 2011, a month before it would have begun play in its third season.  The league had stated that the Colonials could be brought back for the 2012 UFL season, if it were to be played, but the announcement of the 2012 season removed Hartford's logo (which had remained on the site in 2011, with indication it had been suspended) from the UFL Web site and did not include the team in the league's 2012 schedule.

Las Vegas Outlaws (XFL): The Las Vegas Outlaws were an American football team in the XFL.  They played in the Western Division with the Los Angeles Xtreme, San Francisco Demons and Memphis Maniax.

The Hoyas were coached by Craig Esherick and played most of their home games at the MCI Center in Washington, DC, although they played some home games early in the season at McDonough Gymnasium on the Georgetown campus.  The Hoyas were members of the West Division of the Big East Conference.  They finished the season 25-8, 10-6 in Big East play.  Their record earned them a bye in the first round of the 2001 Big East Men's Basketball Tournament, but they lost to Seton Hall in the quarterfinals.  The first Georgetown men's basketball team to appear in the NCAA Men's Division I Basketball Tournament since the 1996-97 season and the last one to do so until the 2005-06 season, they reached the West Region semifinals of the 2001 NCAA Tournament before losing to Maryland.
