The first acquaintance of Israeli basketball fans with James William Nunnally, a native of San Jose, California, was in 2014/15. That season began for him with Spanish side Estudiantes and from there he moved in the middle of the year to Maccabi Ashdod. In 24 games in the Israeli Premier League he scored 17.1 points and averaged about 8 rebounds per evening under the guidance of Tzvika Sherf.
From that point Nunnally's career took off. He played with Italian team Abelino and the following season (2016/17) made the big leap and signed with Fenerbahce. In Istanbul he completed two years under Zeljko Obradovic - He ended the first as European champion and finished the second with a loss to Real Madrid in the Final Four final, after Fener overcame Zalgiris Kaunas in the semi-finals.
During the 2018/19 season he went to Milan and excelled in its ranks with an average of 15 points per evening and 45% from 3-pts range in the Italian league. In the Euroleague he scored 14.1 points and over 42% beyond the arc. In his two seasons with Fener in the top European competition he shot 45.1% and 55.4% behind the three points line.
Nunnally started the 2019/20 season, which was disrupted due to the COVID19 pandemic, in China and in January of that year he returned to his former team Fenerbahce. Last April he was signed by the New Orleans Pelicans from the NBA and took part in 9 games.
