IT would make a nice 6th man/energy guy off the bench on a contender, but he's not gonna get you to the promised land as a starter. IMO he's too one dimensional of a PG, he keeps forcing the ball to the rim, until he has to be told to diversify his game, and get others involved. In the playoffs he actually had to play shooting guard. I agree, I don't think he will take going to the bench very well either.
Develop Rozier and Smart as PG's and look for another 2 or a 3 that can put some points on the board. The C's need to get athletic bigs in the paint. Noel, while not being a big time scorer will add rim protection, steals, defensive energy, size, quickness, he runs the floor well and still has more upside, he's still really young. IMO he will flourish as the starting center, without having to continually look over his shoulder at Okofor, and Embiid. Plus...Stevens will do wonders for his game.
