I'm thinking about teams that have been drafting in the high lottery consistently over the last 5 years or so, which would be LAL, Minnesota and the 76ers. While you can say that they have a lot of potential, the results have been exceedingly slow to come.
With the one-and-done draft and the draft consequently being a huge crapshoot, is it only wishful thinking that a team can rebuild through the draft, even in 5 years?
