I'm a known fan of Noel. He's a tremendous prospect. He clearly is held back by playing next to Okafor. At this point, it seems more likely we'll see Okafor traded. Noel's stats starting at PF vs starting at C are night and day. In the 11 games he's been allowed to start at Center this season, he's averaged 14.2 points, 8 rebounds, 1.4 assists, 1.7 blocks and 2.0 steals in just 28.3mpg. He's doing that with 64% shooting while at PF he's shot 46%.
Project that out to 36 minutes and you have 18 points, 10.1 rebounds, 1.8 assists, 2.2 blocks, 2.5 steals.
Sure it's only 11 games, but he showed this kind of progress last year... after the all-star break he averaged 13.1 points, 10 rebounds, 1.9 assists, 2.3 blocks and 2.1 steals with 49% shooting in 32mpg.
I think any trade for him starts with Marcus Smart. I think Philly would have better options, though and they might just decide to trade Okafor instead. Seems a lot of philly fans think Noel will fit better next to Embiid (who I think is most likely going to play next season), but if Embiid actually comes back healthy and plays as well as they expect, you might end up seeing both Okafor and Noel eventually traded.
