It's obvious the Sixers are going to blow up the team and hopefully the front office after the season.
One of the first moves will be to find if anyone will take Horford's contract. There may be one or two takers. The first may be the Wizards. They are the worst position any NBA team can be. They have huge, unmovable contracts and are stuck in the 8th-10th place in a conference. They aren't good enough to make a run nor are they bad enough to get a good draft pick. If Bertans doesn't want to sign with the Wiz, maybe the Sixers can offer Horford for Bertans and Ish (and maybe a small salary to make it work). Horford would work well with Beal and Wall and at least they'd get something for losing Bertans. Even without Bertans, the Wiz can't sign anyone. If Wall and Beal are healthy, they won't end up at the very bottom of the conference. They might as well try for the eighth slot.
I'm not sure where else he could land. Maybe a three way trade with Atlanta. Horford would be a great mentor for Collins and Young. I don't think they are all that much in love with Capela. Either Reddish or Hunter could be available. The Sixers could keep one of them and move Capela to a third team for someone else.
Hoopshype says the Cavs are trying to put together a package for Simmons. I can't imagine what they have that the Sixers would want. However, maybe the Bulls might be a landing place. He'd fit in well with Lavine and Markinen. The Bulls could trade Coby White, Wendell Carter and one or two non-protected 1st round picks.
