FUTURE FATHER-IN-LAW WAYNE GRETZKY
Wayne Gretzky is going to someday become Dustin Johnson's father-in-law. He practically is already, serving as The Great Grandpa to Johnson and Paulina Gretzky's son. The two play golf together often, though they don't typically compare what it was like to dominate the National Hockey League with trying to maximize his talent on the PGA Tour.
