NBA players are known for their extravagant lifestyles and often splurge on unusual and bizarre purchases. Here are some of the weirdest things they have bought. For example, former player Gilbert Arenas spent $3,000 on a hologram machine that projected images. Another player, JaVale McGee, bought a pet shark and had it installed in a custom-made tank in his home. Dennis Rodman, known for his eccentricity, once bought a $6,000 crystal-covered fur coat. These purchases demonstrate the offbeat and extravagant spending habits of NBA players.
