Cantlay: going pro or staying in school?

Even though many reporters couldn't believe it, Patrick Cantlay re-iterated his decision to stay in school, not just next year, but all four years until he earn's a degree. Funny how reporters at the U.S. Open couldn't believe it. He was asked four different ways if he was staying and why he would. Golf is not a contact sport (except for the part of the ball hitting the face of the club). Sure, he could get injured, but staying at school, playing Riviera and Bel-Air and earning a degree before he hits the PGA Tour is a good idea. Why is that so hard for people to accept? This isn't the NBA, where you're guaranteed money. You dont' make a cut, you don't make money that week on the PGA Tour.
