I look at other teams like Miami or the Thunder, for example, who have gotten guys from summer league or the G league that have made positive impacts on their team, and then I look at the Kings and I don't see anybody of that sort.
You realize that a lot of that is merely good fortune? Every team with a developmental squad has hopes of finding talent just the same. You named two teams, which neither are turning out super studs every few years.
That said, seeing how the developmental league has grown and ‘developed’ over the past decade, we’re starting to see more NBA players come from it. And the trend is likely to continue to the point where it’s more akin to how MLB develops future stars.
I think G-League and all NBA franchises use of it is still at a stage where the sample size is small enough not to know that any one franchise is better or worse at it. Hell, a couple franchises still don’t even have a developmental team yet.
And the ones that have had one were limited in the players they could retain thus reserved in how much time and resources they devoted toward it. However rules have slowly been changing in that regard (2-way contracts, branding, etc.), so we should start to get a better grasp over the next few years.
