Off topic question about jerseys and equipment. Does each team have a dedicated in-house supply of jerseys, so when a player decides to swap jerseys with an opponent, they just sew up a new one with their name and number? Do players pay for throwing their gloves into the stand? Do they get new uniforms each week, or are they actually laundered. What happens to old ones - probably be attractive to collectors. New shoes? (They need better cleats). Must be a huge side business or expense for the teams.
