Nobody will beat the King in terms of working the golf crowd. If anyone gets within a mile of Arnie from the new generation, it will be Rickie. Have you been to a golf tournament lately? Look for the kids dressed in orange, there will be more than a few. The kids liking him leads to their parents liking him and it snowballs. Rickie just does classy things (paying tribute to Payne at Pinehurst with the Plus 4s, paying tribute to Arnie at API, paying tribute to a dying fan at Phoenix, etc). The comparison isn't talent, it's how much the fans want him to win cause they like him.
By the way, Arnold Palmer won his first major at 29. Rickie is 29.
