When discussing the fattest NBA player, it's important to note that the term "fattest" is relative and often used informally. In professional basketball, players are generally known for their athleticism and physical fitness. However, some players have stood out for their exceptional size and weight, which played a unique role in their careers.

One of the most notable players in this category is Shaquille O'Neal, who, during his prime, weighed over 320 pounds. Shaq's sheer size and strength made him a dominant force on the court, contributing to his success with teams like the Los Angeles Lakers and Miami Heat. Another significant name is Greg Oden, who, despite his career being marred by injuries, was known for his robust physique, tipping the scales at around 285 pounds.

While these players are recognized for their weight, it's essential to appreciate their skill and impact on the game. Their size was not just about heft but also about how they leveraged it to become influential figures in the NBA.
