"reverse lottery."
How about this idea of the reverse lottery, where the 14th best record would get the most balls? Also, I would make it that the 14-10th place teams would get an higher probability of getting the 1st overall pick (say 15-20% chance) vs what the current system has for the top 5 (9-25%).
Teams would be fighting for the 8th seed or a 15-20% chance of getting the top pick. This would give the NBA a better product (ie, PHI wouldn't just dump Evan Turner for a ~14M 2nd round pick).
I feel this rewards winning, ensure smarter contracts, & instills the game's integrity. Look if PHX doesn't get the 8th seed, they deserve the 15-20% chance for "Wiggins" & as of today, UTA would get the 6th position (vs 8th).
I like your idea but what about the teams that are not trying to tank, but just suck. The bucks in my opinion are not trying to tank they just do not have enough talent to compete. The problem with a playoff system for sucky teams (other than its not allowed by the CBA) and the reverse lottery is that teams that suck are not always trying to lose. They need help to get better. Now what Philly did should not be allowed they are really tanking games. The Bucks just don't have enough talent.
