Jordan Spieth is not winning the Grand Slam.
This has nothing to do with Spieth himself, a historic, young talent who won his first major nine months after turning an age that allowed him to legally drink the celebratory champagne; a 21-year-old who has two majors, making him the youngest to achieve that feat in 93 years; and a fearless athlete who has, at minimum, a fistful of Grand Slams in his future, not to mention a possible golf rivalry with Rory McIlroy, the likes of which hadn’t been seen since Jack Nicklaus and Tom Watson.
