He was selected in the first round, 25th overall by the Jets in the 2015 NHL Entry Draft.  The Jets acquired the draft pick in a trade that sent Evander Kane and Zach Bogosian to the Buffalo Sabres in exchange for Tyler Myers, Drew Stafford, Joel Armia, and Brendan Lemieux.

It opened in 1994 and is targeted toward younger audiences.  Zach's Zoomer was named after Roger Jourden's grandson, and current General Manager

Zach Merrett: Zach Merrett (born 3 October 1995) is a professional Australian rules footballer playing for the Essendon Football Club in the Australian Football League (AFL).  He was recruited by the Essendon Football Club with the 26th overall selection in the 2013 national draft.  He is the younger brother and teammate of Jackson Merrett.

Harry Blackstone Sr.: Harry Bouton Blackstone (born Henry Boughton; September 27, 1885 – November 16, 1965) was a famed stage magician and illusionist of the 20th century.  Blackstone was born Harry Bouton in Chicago, Illinois, he began his career as a magician in his teens and was popular through World War II as a USO entertainer.  He was often billed as The Great Blackstone.  His son Harry Blackstone Jr. also became a famous magician.  Blackstone Sr. was aided by his younger brother (2 years younger) Pete Bouton who was the stage manager in all his shows.  Blackstone Sr. was married three times.  Blackstone Jr. was his son by his second wife.

Louis Slotin: Louis Alexander Slotin (1 December 1910 – 30 May 1946) was a Canadian physicist and chemist who worked on the Manhattan Project.  During World War II, Slotin conducted research at Los Alamos National Laboratory.  He performed experiments with uranium and plutonium cores to determine their critical mass values.  On 21 May 1946, Slotin was conducting a demonstration when he accidentally initiated a fission reaction, which released a burst of hard radiation.  He received a lethal dose of radiation and died of acute radiation syndrome nine days later.  Slotin was the second person to die from a criticality accident, following the death of Harry Daghlian, who had been exposed to radiation by the same core that killed Slotin.  Slotin was publicly hailed as a hero by the United States government for reacting quickly and preventing his accident from killing any colleagues.  He was later criticized for failing to follow protocol during the experiment.

Demon core: The demon core was a 6.2 kg subcritical mass of plutonium measuring 89 mm in diameter, roughly the size of a softball, best known for its involvement in two criticality accidents.  The core was slated for use in a third World War II nuclear bomb, but remained in use for testing after Japan's surrender.  It was designed with a small safety margin to ensure a successful explosion of the bomb.  The device briefly went supercritical when it was accidentally placed in supercritical configurations during two separate experiments intended to guarantee the core was indeed close to the critical point.  The incidents happened at the Los Alamos laboratory in 1945 and 1946, and resulted in the acute radiation poisoning and subsequent deaths of scientists Harry Daghlian and Louis Slotin.  After these incidents the spherical plutonium core was referred to as the "demon core".

Harry Daghlian: Haroutune Krikor "Harry" Daghlian Jr. (May 4, 1921 – September 15, 1945) was a physicist with the Manhattan Project which designed and produced the atomic bombs that were used in World War II.  He accidentally irradiated himself on August 21, 1945, during a critical mass experiment at the remote Omega Site of the Los Alamos Laboratory in New Mexico, resulting in his death 25 days later.

Bogosian was regarded as a complete, physical defenseman who could contribute on both offense and defense; he was rated as one of the top players heading into the 2008 NHL Entry Draft, where the Atlanta Thrashers selected him third overall.  He signed a contract with the team a few weeks after the draft and began the season with the Thrashers, though he missed several weeks of his rookie year due to injury.  In his second season, he tied a team record for goals by a defenseman.
