As a member of the senior Greek national basketball team, Zisis won the gold medal at the 2005 EuroBasket, the silver medal at the 2006 FIBA World Cup, and the bronze medal at the 2009 EuroBasket.
Early years
Zisis started his basketball playing career in 1996, playing with the junior teams of HAN Thessaloniki (English: YMCA Thessaloniki). He was with the club until 2000. The club would later go on to retire his jersey in 2021.
Nikos' high school team was Mandoulides Schools. In 1999 and 2000 he won the Greek national titles among high schools. In 1999 in Jerusalem, Nikos also won the world championship of High school basketball.
In 2009, Zisis left CSKA Moscow, and signed a 2-year contract worth €1.6 million euros net income with the Italian League club Montepaschi Siena.[6] In 2010, he signed a 2-year extension with Montepaschi.[7] With Siena, he won three Italian League championships (2010, 2011, 2012), three Italian Cups winner (2010, 2011, 2012), and three Italian Cup Supercups (2010, 2011, 2012).
Bilbao Basket
In 2012, Zisis signed a 2-year contract, with the second year being an optional year, with the Spanish League club Bilbao.[8]
The next year, at the 2006 FIBA World Championship, which was held in Japan, Zisis hit a game winning 3-point shot at the end of the game against the Australian national basketball team, to give Greece a 72–69 victory. However, in the next game in the tournament, he was hit on the cheekbone and eye socket bone by the elbow of the Brazilian national basketball team's Anderson Varejão. Zisis suffered a severe facial injury that forced him to sit out for the remaining entirety of the 2006 World Championship, as the injury required surgery. Even though Greece lost Zisis, who was their leading scorer the year before at the 2005 EuroBasket, they were still able to win the silver medal (including an improbable upset victory over Team USA in the semifinals) during the World Championship tournament.
At the 2007 EuroBasket, Zisis was one of the two key Greek players, along with Theo Papaloukas, that led Greece's national team to the biggest comeback in the history of the EuroBasket, against the Slovenian national basketball team. The comeback was called "the miracle". Greece finished the tournament in 4th place.
After the conclusion of the 2015 EuroBasket tournament, Zisis retired from the senior Greek national team.[25][26] Zisis finished his national team career with Greece, having won a total of ten medals at all levels, eight of which came in FIBA competitions. In 2019, the Hellenic Basketball Federation honored Zisis, in recognition of his contributions to the senior Greece men's national basketball team, with which he had 189 caps (games played).[27]
At 1.97 m (6 ft 5 3⁄4 in) tall, Zisis played mainly at the point guard and shooting guard positions, while also playing sometimes at the small forward position. Over his playing career, his primary position with his pro club teams was point guard, while his primary position with the senior Greek men's national basketball team was shooting guard. During his playing career, Zisis was known as "The Lord of the Rings", because he is the Greek player with the most combined medals won at the cadet, junior, young men's, and senior men's European and world FIBA tournaments.[30]
