Panagiotis "Notis" Giannakis, alternatively spelled Panayiotis Yiannakis or Yannakis, is a former Greek professional basketball player and coach. He is considered to be one of the greatest sportspeople of Greece. He started his senior career at the age of just 13 at Ionikos Nikaias and after noticeable success, he achieved extraordinary success as a player with Aris Thessaloniki from 1984 to 1993, in partnership with Greek basketball's biggest star Nikos Galis along with the rest of the squad, while achieving victory as the national team captain in EuroBasket 1987 in Athens, Greece's first major tournament win in non-Olympic sport which, along with Aris' extraordinary success, cultivated the sport in the country. At the end of his career, he won the EuroLeague with Panathinaikos in 1996 As head coach, he most prominently led Greece to its second European trophy in EuroBasket 2005 at Serbia and Montenegro, where a team of new and talented stars shone brightest under the nurturship of Giannakis. He would repeat the success the next year, acquiring the silver medal at the 2006 FIBA World Championship in Japan, where the team most notably scored a decisive win against the USA stars of the NBA in the semi-final, which would be USMNBT's last loss in a tournament until 2019. However, Greece's arch rivals Spain would defeat Giannakis' team in the final, as they would do again in the semi-finals of the 2007 EuroBasket. Outside of the Greek national team, he would coach Greek clubs like Aris, where he had the most success as player, Olympiacos, where he achieved renewed success, and the China men's national basketball team. As a player, he was primarily a point guard, but he could also play at the shooting guard position. During his playing career, Giannakis was also widely-known under his nickname of "O Drákos", or "The Dragon" in English.
