I didn't argue the Lakers are good at drafting. I'm just suggesting that if you look at the majority of NBA teams and take only late first round and second round picks, it won't prove to have a high number of quality players. There are exceptions. My guess is that Spurs would have a higher number of successful late first round and second round picks. I think the Knicks had some pretty solid success with guys like David Lee and Nate Robinson outperforming where they were drafted. But once you get out of the lottery in most drafts, it's not easy to have a lot of success.
I think the Spurs are more of the exception than the rule.
And with that, I decided to look at the Dallas Mavericks, a successful franchise for over a decade who would have quite a bit of late first rounders because of that success.

I tried to make sure I took into account draft day trades to include guys Dallas didn't technically draft and take away guys they drafted but traded right away to other teams. I'm not sure if it's all accurate but it should be close. This is a good team, good franchise that has had a lot of success in the league over the past decade and has good international scouting and has taken chances on international prospects. When it comes to late first round and second round picks, I don't see them having had much success either. I'd guess it's rare to, at least to the extent a team like the Spurs have had.
