Wow. This is exactly what jazz fans should try to stop. Lets take okc as an example. Lets say KD gets hurt in training camp so OKC just decides to tank the whole season. They keep out Ibaka because of his leg injury. However because Westbrook is a star they barely miss the playoffs. I dont want a system where OKC can get the number 1 pick because of one sorta down year due to one star being injured. The weighted system insures that the truly bad teams get the best picks. It also prevents one year tanking scenarios.
But how is a team 'bad' though? Geographically what makes MIL worse than IND? With clever FA signings and drafting (Hibbert & George were not top #5 picks), they were able to build their team the right way.
I would rather have an environment where all 30 teams try their hardest to stay competitive, and whoever they get in the draft is just an added bonus at the end of the year - not something they have to rely on.
