As one of MLS' founding clubs and one that put an MLS Cup in its trophy case in 2000, Sporting KC uses a whole lot of history and good will to keep fans coming through the gates of Sporting Park. Those are fans who remember this team as the Wizards or, simply, The Wiz, before MLS decided to get more soccer-specific in 2010.They remember going to games in cavernous Arrowhead Stadium, rooting on U.S. Men's National Team veterans such as Alexi Lalas and Tony Meola. They also remember, as Sporting reminded them last year when it defeated every U.S. soccer team in its path en route to winning the the U.S. Open Cup, that their soccer team is the closest thing their town has had to an elite professional sports franchise in some time.
