Building through the draft is luck? Well duh...
Tanking is all about increasing your luck by getting into a higher draft position. Also, how can the article just throw out examples like the Spurs and OKC? Yeah they relied on luck, how does that discount it though? Where would the heat be if they didn't draft Wade 5th overall? Boston tanked for a pick, and used it to trade for KG...
"Oh look, teams that win less than 20 games don't win more games in the future." Well no s***, that's because most of them never intended to tank anyways, they're just really dumb!!!
