It's not raining on Johnson's parade

Dustin Johnson's two wins have come in the cold and rain. Why? Johnson has a theory on that related to his four years at Coastal Carolina.
``Well, cold and wet, it doesn't really bother me,'' Johnson said. ``You know, I really learned to play in it in college because it didn't matter what the weather was, my coaches made us play, practice, whatever, so we didn't have a choice.''
