Bradley's Tackle, Dumbest Move of the Gold Cup

Following the US-Canada game I felt obligated to write something about not only how Canada might have been robbed, but also how Michael Bradley's tackle was inexcusable and maybe the dumbest move of the Gold Cup. For starters to use a little soccer common sense, you are winning a game 2-1 and the opposing team picks up the dribble at the top of there own D, so what do you do?
