They are members of the Atlantic Division of the Eastern Conference in the American Hockey League (AHL), and are the AHL affiliate of the Carolina Hurricanes of the National Hockey League (NHL).  The Checkers play their home games at Bojangles' Coliseum.  The current organization is the third team by this name; it succeeded a Checkers franchise which played in the ECHL from 1993 until the end of the 2009–10 ECHL season.  The original Checkers team played in the city from 1956 to 1977, originally in the Eastern Hockey League and then in the Southern Hockey League.  The franchise is one of five teams to directly replace and share a name with a predecessor from a lower-tier league; the others are the Bakersfield Condors, Ontario Reign, Rockford IceHogs, and San Diego Gulls. The 2013–14 Toronto Maple Leafs season was the 97th season for the National Hockey League franchise that was established on November 22, 1917.  Due to a realignment that was approved on March 14, 2013 by the NHL's Board of Governors, the Maple Leafs played this season in the eight-team Atlantic Division of the Eastern Conference.  For the first time since the 1997–98 season, they played every team in the league at least once both home and away.  In fact, they played the Canadiens and the Sabres five times each, every other team in their own division four times each, teams in the Metropolitan Division of the Eastern Conference three times each, and every team from the Western Conference twice. The Prince of Wales Trophy, also known as the Wales Trophy, is an award presented by the National Hockey League (NHL) to the Eastern Conference (formerly the Wales Conference) playoff champions, prior to the final series of games for the Stanley Cup.  Named for Prince Edward, Prince of Wales (later King Edward VIII and then Duke of Windsor), the trophy was first presented in the 1925–26 NHL season to the champion of the first game in Madison Square Garden and then subsequently presented to the champion of the NHL playoffs (including the previous two seasons).  However, the trophy has been awarded for eight different accomplishments throughout its history, including for the American Division regular season champions, the NHL regular season champions, the East Division season champions, the Wales Conference regular season champions, the Wales Conference playoff champions, and the Eastern Conference playoff champions.  The current holder of the Prince of Wales Trophy are the Pittsburgh Penguins, after winning the 2017 Eastern Conference Final. The Pittsburgh Penguins are a professional ice hockey team based in Pittsburgh, Pennsylvania.  They are members of the Metropolitan Division of the Eastern Conference of the National Hockey League (NHL).

The Penguins played in the Civic Arena, also known to Pittsburgh fans as "The Igloo", from the time of their inception through the end of the 2009–10 season.  They moved into their new arena, PPG Paints Arena, to begin the 2010–11 season.  They have qualified for six Stanley Cup Finals, winning the Stanley Cup five times – in 1991, 1992, 2009, 2016, and 2017.  Along with the Edmonton Oilers, the Penguins are tied for the most Cup championships among non-Original Six teams.
