This trade idea of Brown for Murphy and Murray + Picks is reasonable but I don't see it making BOS better in the next couple of seasons, even if Murray plays at his best. So for that reason, I would only do it if it has gotten to the point where Brown wants to be traded and you feel you have to trade him.
If you feel that you have to trade Brown, I would rather get Williamson and Murphy + Picks for Brown and Hauser. Williamson, if he plays at his best, is a player who with Tatum can take you to a title. There is risk with him as there is risk with Murray, but the ceiling is higher. The likely line up would be 1 guard, 3 forwards, and 1 center, not conventional, but I am not sure you need 2 guards on the floor. Or let Murphy be a super 6th man. Or go small with Williamson at center. With how well Tatum rebounds, BOS could get away with that.

The problem is that I can't get this trade to work on the Spotrac Trade Machine. Zion does not seem to be counting as outgoing salary for NOP. It does work on the Fanspo trade machine so I don't know if it is just some glitch with Spotrac or if there really is something about Zion's contract that makes this not work.
