LeBron James will not be jumping out of any planes in the event the Philadelphia 76ers win an NBA championship. Sixers star Jaylen Brown said Monday on a stream he told his new teammates he wants to go skydiving if they're the last team standing in the NBA Finals. James made it abundantly clear he won't take part:As the old saying goes, why would anyone jump out of a perfectly good airplane? Brown recently took the plunge — quite literally — in Egypt as he enjoys what's left of his offseason. The five-time All-Star said he had a fear of heights and wanted to challenge himself.
