Athletes will sometimes wear a certain piece of clothing or object on their arm or neck area because they believe it will help them play better in games, which is a lucky superstition.
According to businessinsider.com, former NBA player and legend Michael Jordan, wore his University of North Carolina at Chapel Hill shorts under his Chicago Bull’s gameday shorts. Another athlete who believed in superstitions was former pitcher for the San Francisco Giants Steve Kline. Kline never washed his own hat and wore it every game.
Former Chicago Bears all-pro linebacker Brian Urlacher used to eat two chocolate chip cookies before every game.
