I haven't seen this posted elsewhere, but lost in the Amir signing with Philly was a rumor that it was nearly as sign-and-trade, with us taking back Okafor.
On the surface it made little sense to me (eww, Okafor), mostly because this would add salary, and we're already a couple million short of max room. Furthermore, my base assumption has been that Crowder would start at the 4 with Hayward on the team. But not having max room has been a bit of a hurdle -- keeping Yabusele overseas, dumping Rozier, and dumping Jackson leave us short by a few hundred thousand. It essentially assumes Hayward loves Brad Stevens so much he's willing to leave about a million dollars on the table. And he may be. But it still feels presumptive that he'd do that.
However, if the Celtics acquired Okafor, they'd be $6.6 million shy of max room after keeping Yab overseas and dumping Jackson, but keeping Rozier. Furthermore, Crowder makes $6.7 million and would have fewer minutes available with Okafor on the roster, as well as Brown and Tatum.
Accordingly, I think it likely that Ainge intends to trade Crowder to create the max room that we need if Hayward comes to Boston. Ideally he will acquire a PF that makes a couple million less in the process. If Hayward chooses us, get ready for some surprising trades to follow. Maybe it will be Okafor, maybe someone else. But I do think Crowder is the odd man out if Hayward comes, which is something that I haven't thought until this afternoon.
