I think Okafor looks really good, and Noel looked really good but I don't see the fit together.
On offense I think Okafor is best as the only guy posting up in the paint, where Noel is better as the only guy rolling to the hoop surrounded by shooters.
Saric fits really nicely next to either but I think he would struggle to defend and create from the perimeter at the 3. A frontline of Okafor, Noel and Saric has spacing issues and might not even be very good defending the perimeter.
It'll be really interesting if the Sixers get a top pick and the best available player is Skal. IMO Embiid, Okafor and Noel all are best at the 5, although Noel can play the 4.
