Golf phenom Nick Dunlap talks about going pro: "It was the easiest, hardest decision I've ever had to make"

Nick Dunlap announced at a press conference Thursday that he was leaving the University of Alabama golf team to join the PGA Tour. 

At just 20 years old, Dunlap made waves in the golfing world as the first amateur golfer to win a PGA Tour event in 33 years.

He spoke to CBS News after the announcement about the difficult decision to go pro and how he broke the news to his college teammates two days before going public.
