Joe Mazzulla is pushing for significant changes in the NBA, advocating for a more dynamic in-season tournament structure similar to European soccer. He believes in having multiple tournaments, separate from the regular season, to enhance competition and showcase team depth. Mazzulla is also interested in incorporating an international aspect to the NBA Cup and suggests a loan system for players, allowing them to temporarily join rival teams without permanent trades. His creative ideas reflect a deep appreciation for the strategies and structures of soccer, particularly those employed by clubs like Manchester City.
