Did you notice how so many men in the U.S. Open got the memo to wear the same top?

Pictured here are Max Mirnyi, Feliciano Lopez and Donald Young all sporting Nike’s men’s Global Power Crewneck shirt from the fall 2007 collection retailing for $55. John Isner and Jesse Levine were wearing it, too.

According to a Nike spokeswoman it's fairly typical for players to choose "key performance products" from the company's line. We just must not have noticed it before.
