What your suggesting is almost a complet rebuild
- Play Dak at 60m on an expiring contract or cut him entirely
- Trade our quality players (presumably for picks)
- Let our better (more costly) free agents walk
- Sign only cheap free agents to replace those traded, cut or who walk
Might as well also suggest we actively tank the season and get as high a pick as possible.
Not rejecting the idea but we need to be honest with ourselves and not each other and not pretend that your suggested path is going to result in a trip to the post season because it would not.
