Usually the American team looks like a cross between a 40-year-old father of three and Chandler Bing, so it's nice that someone had the idea to toss some cool digs on these fellas.
Is the retro look a move made because there are so many young guys on the team? I think so. Also, the purple sweater? It seems that might have been a nod at Tiger Woods, who tends to rock purple sweaters when he can.
