Of course. Even if you draft a star in the top 3 you'll end up having them demand a trade in a few years if you don't put pieces around them. 2nd rounders, free agents, GLeague standouts, even late 1sts once your team is too good to pick high.
The Warriors 1st championship team was a bit of an anomaly in that their best two players were drafted #7 & #11 but part of that was hitting on a possible HOF talent in the 2nd in Draymond. But they also went on to add complimentary pieces via trades, free agency, and the draft in Iguodala, Livingston, Barnes etc.
McNair has actually shown a decent ability to acquire complimentary players so far. The issue is the Kings don't have their foundational players. I hoped Fox would take a leap and be one of them but even if he had, they'd need one more star, likely one that makes Fox a solid #2 player at least.
I think that's why a rebuild appeals more now, other than the team being terrible for the 16th season in a row. Because I think we have a competent GM for the first time since Petrie who could actually make it work.
