It's obviously possible to find talent any where in the draft & DL has clearly shown the ability to do so more than others but statisticlly, (again, not sure how reliable the source is) you generally have a higher chance of finding a "star" the higher you pick. Gobert & Mitchell (to a lesser extent) are outliers.
You're right, there are no guarantees so why not give yourself the best odds possible? I agree that avoiding developing a losing culture is important but I disagree that it's more important than giving yourself the highest percentage possible of find a star, especially when we're 1 away from having a legitimate, young, homegrown big 3.
If I believed we had a reasonable chance at making a decent playoff run, I may feel differently. But when seeing that the chance of find a star between #6-10 is 31% & #11-15 is 16%, I can't see a valid argument that we would be better off picking in that #11-15 range.
Not when we're gambling on acquiring the final piece of the (seemingly) biggest requirement to winning a championship these days.
