Assuming this actually goes down they would be on the hook to pay Lauri + Jaylen near $435 mil over the next four years for basically a #2 and #3 option. Neither which are primary ballhandler types. Add in the $150 mil extension they will likely need to pay Kessler. Not sure if that type of payroll is even sustainable. All 3 should have some sort of value for a future trade when they inevitably need to break up that core due to the aprons.
Also I thought part of the reason they dealt Donovan was due to his unhappiness in Utah. Can't imagine Jaylen Brown, the biggest social activist in the league, would be thrilled to be here either. I would highly assume the Ainges should have the inside scoop on that aspect of any potential deal.
It's interesting speculation but ultimately not sure this would be the right path for the Jazz to be taking right now.
