This assumes the Jazz are looking to upgrade their roster. MPJ is a better player than John Collins and I believe is still on an upward trajectory.
John Collins and Aaron Gordon fill a similar role but it can't be bad to have more athletics wings who can shoot a little around him. Jordan Clarkson gives desperately needed guard scoring.
I included the Strawther/Williams swap because I think the Nuggets may be able to get a little bit more out of this deal.
