Tiger Woods finished second Sunday, yet seemed happy. Uncharacteristically, he waited to give a big hug to the winner. Mr. Woods played well, which may be part of his joy. But the other part might just be who won the PGA Championship.

Brooks Koepka won his third major tournament in two years – and is one of the best young players in the game. In a sense, Mr. Koepka is Tiger 2.0. Koepka’s a true athlete, mentally and physically imposing, in a sport that once had a reputation of not being populated by athletes. Woods changed that perception. He made workouts cool. Heck, he made golf cool. Koepka could have been a pro baseball player, like his dad, but he chose golf – and a generation of athletes who grew up watching Woods have made a similar choice.

Sports embodies continual progress, always pushing the boundaries of time and space. Woods redefined the limits of what was possible in his chosen sport.

Thanks to injuries (and "incredibly bad" life choices), Woods hasn’t won a major tournament in a decade. He’s healthy now and displaying his old magic. But his comeback quest is made all the more difficult because of his influence on the sport. Woods is now challenging younger players who modeled their game after his, those whom he inspired as children. And the game of golf is all the better for it.

Now to our five selected stories, including a closer look at fostering innovation in education, law enforcement, and the movie business.
