From that article:
Perhaps my reading comprehension needs work, but aren't Randle, Vonleh and Gordon all top ten prospects who have worked out for the Jazz in Utah?
They are calling smart a top ten prospect. Not all top ten prospects just a top ten prospect. Could be read your way but based on context definitely what the author meant.
it is notable that the Jazz have been unable to bring in a top-ten prospect (smart) with a week left before the draft.
