I can't really judge Dame fairly because I lived in Portland for so long and would get a kick out of it. His defense is indeed trash. On the surface he does seem like a perfect fit for Joel, he can do most of what Harden did with him last year as well as nearly all of what they wanted out of Butler in 2019 (not all of which Butler did then).
But man, doesn't this team just need an old-fashioned point guard? I know that is barely a thing anymore But I don't think Dame would be the facilitator Harden was - and is even more used to the being the man than Harden was. If you're going to have Dame you almost can't have Maxey, find another guard who can play defense and run an offense for others. Of course that would be unwise unless Maxey gets you a piece that really does win you a championship in the next two yeas.
I also don't know that Dame would come here tbh. He is a West Coast dude who wants to play for the same teams Harden does. I think he'd like it though. Portland NBA fans are great but when I finally went to a Sixers game this year the contrast in the atmosphere was profound.
Or he could refuse to leave Portland and we could go get Scoot Henderson
In some ways this is still a game of kick the can no? The Sixers are going to have to take the deal that works when it is in front of them and then figure out other deals, both short and medium-term. And as Harden and Durant and Kyrie and Chris Paul and any other star you can name show, nothing lasts that long anyway.
