The Miami Heat are facing their most important game in history tonight and are asking fans to cheer and not to leave early. The Heat are down 3-2 to the Dallas Mavericks in the NBA Finals and have called in the sixth man to help. In the email sent out to season ticket holders, the Heat tell fans to wear “white and comfortable shoes because “you need to be standing from the opening tip ’til the final buzzer”. Earlier this season, the Heat made a promo video telling fans how to “Fan Up,” after receiving criticism for fans not showing up on time. During the Eastern Conference finals, Charles Barkely called the Heat the worst fans in sports.
