Not so sure about "homegrown talent". MINNY sold the farm for Gobert and OKC got their main star by trade too, then Denver lucked into Jokic in the second round, which you should'nt really bet on every year, right
I beleive it shows taking risks and not entirely building through the draft pays off, becasue it's really hard and rare to get your 2 or 3 stars via the draft, both statistically and techically.
the hardest part is getting your franchise player. From that point on, you should focus on free agency and trades to find your second banana if you ask me because the probalbity you find another star via the draft slims down, specially with a franchise player like Wemby who won't be OK for another tanking year, plus 3-4 years of development for that other hypothetical star.
