Everything would change for me in 2007 when my wife and I moved to Kansas City. There, I was finally able to get intrenched in supporting an MLS team and quickly began to cheer for an exciting Wizards forward named Eddie Johnson. My support for Kansas City was soon equaled by my support for my new/old favorite team, Seattle Sounders FC.
