I was wondering if the NBA logo is modeled after a player and it is. That player is Jerry West. His career stats with an average of 27 points, 5.8 rebounds, and 6.7 assists, per game. The image below is what inspired the logo.
He has been the logo since 1971. There have been some people who want to change the logo to a Michael Jordan silhouette, but I doubt it. Organizations don't tend to change logos after almost fifty years.
