Danny does seem to have a MO of picking guys with tangible skills and a demonstrated ability to play the game, even when they don't have a well defined position and they lack ideal physical tools.
He does not often seem to pick players who are the opposite -- immense potential thanks to crazy physical dimensions / gifts, but unclear if they'll ever learn how to play. The one example that comes to mind is Fab Melo, and we know how that worked out. Fab might have been a good pick if he were 18 at the time Danny drafted him, though.
I don't think it's unfair to suggest that Danny is better than average at finding guys who belong in the NBA and who can contribute. On the other hand, I don't think Danny often finds "home run" guys. Even Rondo seems to me more a "best case" of the former scenario rather than the latter. It's not like Rondo turned into this amazing all-around player. He was just a lot better at the things he was good at than anybody, except maybe Ainge, expected.
Olynyk was not a bad pick. It does appear that Giannis, Gobert, and maybe Dieng and Schroeder will end up as better picks in the long run. But the common thread I see here is that all of the latter group are foreigners, and only one of them played in the NCAA. That may be Danny's biggest blind spot. He just doesn't seem to scout and draft foreigners very often, or very well (yes, I'm aware Kelly is Canadian).
Nobody should get their hopes up about Danny drafting Kristaps Porzingis or Mario Hezonja in this year's draft, I'd say.
