For Stefan Frei, goalkeeping is about denying creation. Frei says the duty of the goalkeeper is to stop the opposition. The task requires perfection, with no room for error, even less for creative expression. For Frei, that void is filled with his artwork, a lifelong passion. Frei is heading a project to create a giant tifo, to be displayed at CenturyLink Field before the Sounders' game against the Chicago Fire Sept. 28.
