I think Detroit also got two seconds did they not? Just because the Kings have traditionally gotten no value from 2nds doesn’t mean that fact is true for all teams.
But if you look at the last eleven years, while the average second round pick has gone up in value to 3.5 WS per pick, the Kings' average value per pick has been 9.6 WS, blowing the average team out of the water. The Kings got that value by drafting Isaiah Thomas and Hassan Whiteside. (And yes, Whiteside didn't earn most of his value for the Kings, but we picked him. The Kings have a couple of second rounders that have put up oretty nice stats for them, including Richaun Holmes, that they didn't pick and didn't get credit for in the above analysis. Fair's fair.)
The fact is that the average value of second-round picks is heavily, heavily skewed by a small number of very good players. In fact, in the last eleven years only five players from the second round have exceeded 40 WS: Nikola Jokic, Draymond Green, Khris Middleton, Isaiah Thomas, and Hassan Whiteside. The Kings selected two of those five. Which is pretty good. Considering that 6% of second round picks account for 50% of the WS value of second rounders, it shoul dbe pretty clear that for all intents, the second round is feast or famine. The Kings have feasted with 2 of their last 10 picks, which is actually a really great hit rate.
And, of course, the book isn't entirely closed on guys like Woodard and Ramsey and it isn't even open yet on Queta.
I get that every fan wants their team to do more with their draft picks. But many fans overestimate what other teams do with their draft picks while underestimating what their own team does with theirs.
