If you want to include the Weisbrod/Benning led process, and judge two covid drafts where Weisbrod said he did it without the title, be my guest. The point still stands even with those two drafts that we have some of the most games played in the league from third round & later picks, and there was all of 1 more more second round pick to evaluatte.
The expected hit rate of picks in the 11-15 range is ~50%, and it looks like we're tracking above that. 2nd round picks are usually around 10-15%, 3rds are ~5%, and 4th and later are 1-2%.
With the caveat that we still need more time to evaluate, the picks are tracking to hit at way above the expected rate. To call it mediocre is to say unless you're like the Montreal Canadiens or Washington Capitals, you're mediocre.
