That's not really true even right now. More like Rubio>>>>Exum. But by next year the difference could be negligible, and then the next 4 years Dante could easily pass him. I think the Jazz are going to lock up Dante, see how things develop next season, and then make a decision. Keeping Exum and assuming he is a rotation player next year will make it pretty easy to trade him if you decide to go with Ricky long term. Ricky could still get better as well with the Jazz developmental program. I think you just keep both guys but make sure to communicate with Dante that he has every license to take that starting job if he earns it. Then you plan to make a choice after next season. Of course if Exum gets a lowish number in FA that might make it easier to keep both for longer if you want.
