There's a guy in your life who's obsessed with basketball. He's got season tickets to his favorite team's home games. You can never take him to a bar with a TV in it during basketball season unless you want to be ignored 75% of the time and assured 25% of the time that he's "TOTALLY paying attention" to what you're saying (he's not). And whether he actually assembles his buddies for basketball games or he's just content to be a superfan isn't important. What's important is that he trades in the collegiate trappings of his basketball addiction (a tattered poster, old tickets tacked to his wall, and the like) for something a little more adult, like these Unofish Leather Basketballs ($249), for example.
At this price, of course, these are not for use on the court, but rather for display in his apartment, man cave, or whereever he wants to put his love of the game on display. They're so well-designed, his girlfriend (you?) won't even be opposed to having them around the house.
