In 2000, the Kansas City Wizards won the MLS Cup championship, in large part on the strength of Tony Meola in goal.
The assumption from many is that Houston will win today and set up a rematch of last year's championship, but I've seen Houston start off slowly in both their playoff games this year. Maybe the rush of goals towards the end of the Dallas game got that out of their system, but I'm skeptical. I also think that Kansas City is building the kind of teamwork and momentum that a squad needs to pull off this kind of upset.
Their current goalkeeper, Kevin Hartman, talked about some of those aspects - guys stepping up to do the little things - after the series win against Chivas USA.
