I preferred PJ3 also, but with Sullinger and Green, it made more sense for DA to draft for position. Melo is an interesting combination of size and athleticism. I liked the way he moved defensively in his first game.
Melo is working with the best basketball skills trainer in the business. I expect him to be a lot better offensive player once the seasons starts. Defensively, he has the instincts to be a good rim protector, and also should be a good cover guy on pick/roll.
Melo, Sully, Green, AB, and Rondo is a nice young core with decent positional balance, and if Joseph becomes an NBA player it will be even more balanced. I'm over them not grabbing Jones.
