Actually they have. Golden state and Cleveland. Golden state was mediocre post the baron, Jackson years. They gutted the team signed David lee to a massive contract. Then they got lucky in the lottery people passed on curry and klay. Jettisoned monta and acquired bogut and Barnes and drsymond. Rest is history. Cleveland was in no mans land as they were an older capped out roster that wasn’t good post LeBron move to Miami. Couple years later acquired Bennett who was a bad pick, Wiggins and kyrie and flip a couple for love rest is history.
