Why he's on the list: Beyond the big money that goes along with big golf wins, Phil Mickelson gave sports fans the heart-warming sports miracle of the year when he won his third Masters. Waiting for him at the 18th green was his wife, Amy, recovering from surgery for breast cancer. CBS announcer Jim Nantz commented on the win—and Tiger Wood's problems—when he said: "That's a win for the family."
