Zack knows everything about his basketball team. He is always confident in giving his opinion on his favorite team. Let's call Zack the fan who knows everything. Don't be surprised because you may have to sit next to one of them during the game. Knowing everything can tell you which player has the highest average points, assists and rebounds. Asking them a question about the basketball team would probably feel like a simple pop quiz. A know-it-all can go far when it comes to talking basketball, however they are nothing like "die-hards"
