By now everyone knows Rory Mac won the US Open. We can talk for days about how non-Americans are winning golf's major tournaments. Does it really matter. The player scoring the best over four days wins, regardless of nationality. The U.S. has plenty of great players. Isn't that enough? Anyway, Rory won big and looked cool doing it. For my money, he has the best golf swing in the game. He is today's Ernie and Freddie wrapped in one. Are we on the cusp of a new era in golf --- the Rory Era?
