America's national championship is the most unpredictable of the majors. Tiger Woods might win, but so could Lucas Glover. Used to be you could count out the Europeans, but Graeme McDowell ended that 40-year tradition in 2010. This will be the third Open at Congressional Country Club in Bethesda, Md. Will it meet the standard set in 1964, when Ken Venturi held on for dear life, or in '97, when Ernie Els thwarted Tom Lehman and Colin Montgomerie yet again? We'll know on Father's Day, assuming that's when this year's Open ends.
