Hawks have to trade Collins, right? He clearly isn't a good fit with Trae and the Hawks need to do something and moving Collins seems like their best bet. Not sure what they could get for him or what team makes the most sense (maybe Dallas), but that seems like something Atlanta needs to do.
How about this
Dallas - Collins
Atlanta - Markkanen, Boban, 26, Dal 24 1st (lotto)
Cleveland - Dinwiddie
Cleveland could then sign and trade Sexton somewhere and get different assets for him since they have Dinwiddie to fill that role. Dallas gets a solid 3rd player and the big man they are lacking. Atlanta gets a nice shooting big man (on a reasonable contract), a bruiser, and a couple of 1st's to help replenish the coffers or to use in a trade.
I agree with you they need to make moves and I would imagine that Collins has more of a market than capela. But they are not in a point with their franchise where they can trade Collins for non immediate contributors (I know Markkanan has a little bit of value but he is really an awful defender). They need to get someone alongside Hunter, trae, huerter and capela that is a two way player. I would also wonder if Nate is on the hot seat. Trae young is talented offensively and it just seems like hawks made zero adjustments that series.
Also I will add it would be absolutely idiotic of the Cavs to get dinwiddie. He thinks he is better than he is and has a reputation of being awful in the locker room. They don’t need to bring that into the good thing they have going healthy.
Trae is still on his rookie contract, so is Hunter, Huerter, and Okongwu. All 4 of those guys are 24 or younger, I just don't buy the idea that they have to win now. Sure it would be nice, but let's get these guys at least onto 2nd contract at least before we start really pushing the winning. I just don't think Collins fits all that well with them, while I do think Markkanen would. I think he'd be a pretty nice long term fit with Okongwu and the small guys.
