That information seems confused to me. The article clearly says:
"Later Paul told ESPN Bazeley will receive $200k in base salary over five years,
if he remains on an NBA roster in the second year and is in the league each season thereafter."
I don't see a firm answer to how much the 3 month internship pays or what he gets before he makes an NBA roster, if anything. The fact that they call it an internship and not a job, suggests it probably doesn't pay much. But that statement, pretty clearly says his $1 million ($200K annually) is contingent on him making an NBA roster after this upcoming draft (in the second year out of high school) and being on an NBA roster for each of the next 5 years thereafter in order to get the annual $200K payment.
It sounds like all that was done for him was to limit his upside. If he gets a rookie roster spot following the draft, I assume he isn't going to have a problem getting a shoe deal. If he makes a big splash in his first year, New Balance got a huge discount here.
Congratulations on a whole lot of nothing! Well that's not entirely true, Rich Paul and Lebron James got a whole lot of ink and Darius did get an internship. If he doesn't get drafted that internship will come in handy if he wants to apply for a big corner suite office job at Nike.
