Another Star Wars fan
We can get pretty attached to the players of our favorite team, and some of the hardcore fans even go as far as wishing they were personally involved with the players. This man, for example, seems to think that Dirk Nowitzki is his brother. This seems like an odd way to express your love or support for a player, but we’re sure he’s seen stranger things by now.
He also happens to be a Star Wars fan, and he probably wanted to make the crowd laugh. Of course, it could also be that this fan really happens to be Nowitzki’s brother, but then, why would he need to publicly announce it during the game? Either way this seems like a strange sign. Would you attend a basketball game holding a sign like this?
