I think he'll be successful in the league no matter what. There's always a place in the NBA for his skill set, which he has refined extremely well over the course of this season. But HOW successful is the question. He does tend to avoid physical situations, he's not a great rebounder, and while he's a great iso player, he could do a better job of moving without the ball. A major problem for Hood right now is that, when Jabari has the ball, Hood kind of takes the play off and watches Jabari go to work. He'd be wise to start using his size and length to get into the paint to grab some rebounds, because Jabari isn't bullet proof. He'd also be wise to take off his concrete shoes when Parker has the ball.
If he can do those things, I think, with DX projecting him to go in the mid-teens, he'll be the steal of the draft. If he doesn't fix those things, he'll be worth exactly where he's projected to go.
