San Antonio, Utah, Toronto
I'm not sold on Toronto as a team that consistently drafts well but that's neither here nor there.
Teams with a strong/stable organization and culture to go along with a good scouting department will have more success and I think that's what you see with Utah, San Antonio, and a few other teams. I think that's the best you can do to take the luck out of it. I think it's similar to any organization. Good talent fails all the time in bad situations and lesser talent succeeds all the time in organizations with good support.
