In
1999 after completing his military service with the
Israel Defense Forces, at 24 years of age Shamir spent one year training under
Rick Pitino at the
University of Kentucky, which according to him affected him profoundly. He then led the Hapoel Jerusalem U-16 team to the state championship, and worked with the U-18 team. In 2001, Shamir was named the assistant coach of
Hapoel Jerusalem under head coaches Yoram Harush and
Erez Edelstein. He led the team to two consecutive
Israeli State Cup titles, in 2007 and 2008. In 2011, Shamir was named the head coach of
Hapoel Holon. In 2013, Shamir was named the assistant coach of
CSKA Moscow under head coach
Ettore Messina. Shamir helped CSKA win the
VTB United League title, and reach the
2014 Euroleague Final Four, where they eventually lost to his former team Maccabi Tel Aviv. In 2014, Shamir was named the new head coach of
Hapoel Eilat, signing a two-year deal. On November 27, 2015, Shamir returned to Hapoel Holon for a second stint, replacing
Elad Hasin. In the 2016–17 season, Shamir led Holon to the
2017 Israeli League Playoffs as the first seed, but they eventually were eliminated by
Maccabi Haifa in the Quarterfinals. On March 5, 2017, Shamir signed a two-year contract extension with Holon. In the 2017–18 season, Shamir led Holon to the
2018 Israeli State Cup title, and it reached the
2018 Israeli League Finals. On June 14, 2018, Shamir was named the
Israeli Basketball Premier League Coach of the Year. In the 2018–19 season, Shamir led Holon to the
2019 Israeli League Playoffs and the
2019 FIBA Europe Cup Semifinals, where they eventually lost to
Dinamo Sassari. In July 2019, Shamir was appointed Director of Basketball at the
New Zealand Breakers, joining them as head coach and in an off-the-court role. In the 2019-20 NBL season, the Breakers finished with a 15–13 record and did not qualify for the playoffs. In the 2020-21 NBL season, the Breakers finished with a 12–24 record and again did not qualify for the playoffs. Despite missing the playoffs in both of his first two seasons as head coach, Shamir was offered a two-year contract extension in July 2021 to remain at the club until at least the 2023-24 Australian NBL season. In the 2021-22 NBL season, the Breakers finished at the bottom of the league with a 5–23 record, which was the Breakers' worst finish in franchise history. On May 11, 2022, Shamir resigned as head coach of the New Zealand Breakers, with lead assistant coach
Mody Maor being named as his replacement later that day. == References ==
