How about flip this around some and do a trade along these lines:
Brown + Hauser
for
Zion + Murray + Picks?
NOP keeps their good young player in Murphy, which makes sense they would want to do. BOS gets Zion, a potential upside players with some risk and a vet guard who is actually pretty good. I think NOP would include at least 1 first with this as well.
It adds about $7M to BOS salary, so limits flexibility, but results in a pretty well balanced team:
Murray
White
Tatum
Zion
Queta
what would be the point of this? C's send out the best player in the deal for 2 guys with injury histories and do not get back the most desired player NO has. The draft capital doesn't come close to making up the difference no matter how many NO includes because they only have their own to trade which will only be picks in the 20's if NO has Brown and Murphy and the rest of their roster
We are just spit-balling trade ideas. The main difference between Murray and Murphy is that Murray is a better fit positionally. I don't buy that Murphy is a guard. He is a forward. A promising young forward but if you have Tatum, Zion, and Murphy, the forward position is a bit crowded. Murray is a guard and was a pretty good one before his injury. Guard is a better fit on a team with Tatum and Zion.
I don't think it is likely that Brown is traded (I keep saying that). But it is still fun to test out possible trades because I think there is some possibility that Brown would like to be traded. Zion has huge risks but some here think he is better than Brown. There is a chance that he will be as good if not better than Brown for the next 5 seasons. I think the chance is slim, but it is a real possibility. If that happens, this would be a really good trade. If Zion eats himself out of the league, this would be a really bad trade. Those are the extremes.
You know who else is a SF that plays shooting guard? Jaylen Brown. Murphy can easily play the 2. He?s bigger and a better athlete than JB.

You may know Murphy's game better than me. He feels like a forward, but I don't know. Jaylen is 6'-6", Murphy is 6'-8". Jaylen can certainly play either, defend either. I am not sure you want either handling the ball all that much, as you expect with a guard. Murray is a guard and to me is much more suited as that combo guard role, like Holiday, different than Murphy or Brown. And that is a need many talk about.
The team was at its recent best with Holiday, White, Brown, Tatum, Porzingis. I see the closest you can get to that is Murray, White, Tatum, Zion, and Queta. Positionally, I like that better than White, Murphy, Tatum, Zion, Queta. Not saying that Murphy doesn't have more value than Murray, just saying he is a better fit positionally for the team right now.
