Jim Boylan was relieved of his coaching duties and ex-Atlanta Hawks coach Larry Drew was hired. On June 27, 2013, the Bucks chose Greek forward Giannis Antetokounmpo with the 15th overall pick of the 2013 NBA draft. They also brought in O. J. Mayo, Carlos Delfino, Zaza Pachulia, and Gary Neal as well as seeing Monta Ellis opt out of the final year of his contract. The Bucks also agreed to sign-and-trade Brandon Jennings to the Detroit Pistons in exchange for Brandon Knight, Khris Middleton, and Viacheslav Kravtsov. The Bucks later extended their contract with Larry Sanders with a four-year, $44 million contract and traded Ish Smith and Kravtsov to the Phoenix Suns for Caron Butler. By the start of the 2013–14 season, the Bucks only had four players on their roster from the previous season. The season itself was a struggle, as the Bucks finished with the worst record in the league at 15–67, the worst record in team history.
