This trade would be beneficial for all the teams included in it. For a championship run, it's needed to have some experienced vets; for 76ers, it's Wall and CJ. On the other hand, Blazers could finally form a big 3 to contend in the west. When it comes to the Celtics, they can get the big they desperately need. And with decent role players, it would make them serious contenders as well. Last and least, Rockets get first round picks and seconds too. Also getting vets like Al and Harris would've been great for young guys to have true role models in these two gentlemen.
