hmm, I don't see it that way. if healthy they are one of the best frontcourt tandems in the league. if the Jazz can somehow re sign Millsap for a reasonable price, they will have a big rotation that is as good as any in the league. If it doesn't work, either Boozer and Okur will be very valuable trading chips at deadline.
considering the Jazz are closer to being contenders than to rebuilding, this isn't a bad situation. and next season they will also know better what they can expect from Koufos and let Okur walk, if Koufos is ready.
so IMO they are not screwed. in fact their overall situation looks pretty good.
(of course, assuming they are willing to pay some lux tax)
