I wanted Montrezl Harrell with the pick, but RJ was the other obvious choice at that position in the draft. He and Young have some similarities in that they both had big moments in college and that probably increased their draft stock; it's a shame neither of them can really shoot in the NBA, though (yet).
With so many picks on the horizon, it is hard to see Danny sticking with either of them unless we have a big quantity for quality trade. Even if that's the case, I imagine at least one of them is getting shipped out. Neither is particularly valuable right now, unfortunately.
