I saw some tweet about how awful life is on the road in the G-League and how Duke has such state of the art facilities. Sorry but if you ask me, if I want to make $125,000 at 19 or have an internship with a company that has a really really really building and a free cafeteria, it is an easy choice, except if the internship gets me to the NBA draft while the job doesn't.
So the only reason to go to college under those circumstances is if college is more likely to get you drafted or get you drafted higher. Actually enough guys who would have been none and done are not one and done after a year in college that I am surprised more guys don't do what Anfernee Simons did last year and take a post high school grad year and then get drafted. It would be quite rare for a none and done guy to have a bad enough prep school year that the went undrafted. On the other hand that can happy fairly frequently in college, the G-leauge or overseason.
