It will be interesting to see if Jackson tries to go straight into the NBA draft. He turns 19 in February, so he's got the age thing covered. It would come down to technicalities about the rule, whether attending a "Prep School" is the same as a HS, and what, exactly, "graduating class" means. There are some interesting potential loopholes in how the NBA draft rules are written, because it's not as clear-cut as "19 years old in the year of the draft". Thon Maker could be another case like this, since he's apparently only going to play 1 semester in college. It's easy to assume he's eligible for the draft, but if he doesn't graduate HS until after June, then is he really 19 AND one year removed from his graduating class (which is what the rule is right now)?
