Maybe for the same reasons that the Canadian hockey players-who mostly live, and earn their living in the U.S.- were so eager to win the gold for their country?
US Hockey team players Paul Statsny, Zach Parise and Ryan Malone’s fathers were former canadian hockey players who later became US citizens.
Ray Bourque’s son (yes, the NHL Canadian great) played for the gold winning American team World Jr’s IN Canada last Dec 26, which shocked canada.
Scott Niedermayer’s kids were born in America, so’s Gretzky’s, icnluding Canadian coach Mike Babcock. It doesn’t necc say that their loyalties are with canada as per my examples.
