U.S. team: Seattle Seahawks (NFL)
Soccer team: Seattle Sounders (MLS)
Sure, the Microsoft co-founder and his Seahawks added a Super Bowl win to their history and a Lombardi Trophy to their case at CenturyLink Field, but Allen's soccer accomplishments are only slightly less remarkable.
The Sounders have drawn more than 40,000 fans to each match since joining Major League Soccer 2009. That's not only the best attendance in Major League Soccer, but regularly better than the crowds drawn by Major League Baseball's Seattle Mariners just across the street.
Thanks to a $9 million payment to Premier League club Tottenham Hotspur last year and $5 million a year after that until 2016, U.S. captain Clint Dempsey is now a Sounders fixture. Two of his Seattle teammates -- midfielder Brad Evans and defender DeAndre Yedlin -- also made the cut for the U.S. team and joined Dempsey in Brazil.
It was once an accepted soccer truth that U.S. players had to be culled from European squads if they were expected to be any good. The Sounders are doing their best to debunk that notion.
