Why though? It ties into my original argument for Ex. The fact is that none of the Lakers' young players were good or developed correctly until after they left the team that drafted them. Whether that's because of the losing culture, or the Lakers' particularly bad PD department, is not clear. I believe it's more the former, and there's a long list of players drafted into tanking teams and losing situations (where they weren't actively told to throw games, mind you) that failed to develop properly because of it.
Filling a team with youth and hoping they'll develop without vet guidance or a good culture to grow into is a recipe for disaster, IMO. Sure, the teams might finally grow into better players - once they're off your team and onto a better one. Not much use for us if we were to go that route, considering the low attractiveness of SA as a market.
