This really isn't news. Everyone is well aware that Okafor and Noel weren't able to show their star potential when forced to share time together. Everyone knows they are open to trading one of them. Everyone knows that at some point they will probably move one.
What's not mentioned in this article, but generally accepted by everyone, is that Philly probably isn't getting great offers for either player right now.
My point has been that Philly doesn't actually NEED to trade either right now. Especially if the offers are weak. They can (and probably should) go into this season with all their bigs, see how things shake out, see if either of those guys makes a leap, see if one of those guys forms great chemistry with the new players (Embiid, Saric, Simmons, etc), see if offers improve, and make an educated decision when the time is right. Whatever weak offers they are getting now will probably still be available to them at the trade deadline.
Like the rest of everyone here, I hope Boston is the team that snags one of these star big man prospects. It's a little cringe-worthy to celebrate the perceived lack of trade value when neither has yet been traded. If a pennies on the dollar trade is made such as Okafor for Smart + Rozier, then you can celebrate the acquisition of a potential offensive phenom big man. Until then, Philly holds the chips and anyone who wants one of those bigs has to meet their demands.
