So as of now, the Clips are on the books for $56M for next year, leaving them roughly $10M for free agents. They could get down to around $46M by cutting Crawford and Barnes with their team options next year, though that seems unlikely. This also isn't accounting for DJ being a free agent and presumably wanting something near the max this summer. They also have virtually no trade assets that aren't core pieces.
This team really doesn't have any good avenue at improving their team much, and resigning DJ will really hamper them even more. Hopefully they look for a cheaper option and let DJ walk. Unfortunately, GM Doc has wood for DJ, and he'll probably give him the max. They're extremely top heavy in salary, and it's killing their flexibility and maneuverability.
