I think Hinkie's plan was doomed to fail because he just didn't take into account the human element involved. His plan was all about the numbers. The plan called for losing the most games, garnering the most ping pong balls, reducing the chances of missing in the lottery, drafting, rinsing and repeating for several years, all while collecting assets. Then, hopefully, you will have found one to three stars and some other assets and then attempt a coup of an off season by pulling an Ainge 2007-08 move and trading the assets to add to the stars and be a contender.
Sounds easy, and it is! It's a simple thing to do if you are playing a game like NBA2K16 or fantasy basketball. You can do those things when people are just numbers but you can't do them in real life.
The human element is ignored in the above games. There's no fan base to have to appease, you know, the humans that show up at games and spend money or show up at places to buy team paraphernalia. Keeping fans interested and happy is the name of the game in the NBA. Its an entertainment industry and you have to keep the customer coming back. Horrific losing done on purpose over years, does not keep the customer coming back!
Tanking like Hinkie also doesn't account for how players and coaches will react. Extended losing sours both players and coaches and makes it so they don't want to stick around or give their best effort when they know that management's goal is not to win. Personnel management is one of the most important parts of any strong business and this treatment of players and coaches goes against everything a company should do in creating the optimal working environment for their employees to succeed.
Add in the alienation of player agents and other GMs who look to you as a source to please their clients or bosses through signings and trades and you have cut off your ability to work at optimal capacity within the NBA environment. Suddenly the league is getting complaints from owners and agents about the way you are doing business and the league starts to question whether you are hurting the league's overall appeal. They start calling into question whether you are playing fast and loose with the integrity of the game.
When dealing with humans as a product for sale(entertainment), one must always take into consideration the unpredictable variables that human emotion and behavior bring into the equation. Hinkie ignored this completely. By not fostering an environment of winning and development, he doomed the people in his system to failure. By not caring about winning, Hinkie p!ssed off his fan base who have been leaving the team in droves. By not working in a professional manner as other GMs have by looking to improve the team through signings and trades, he has created a situation where other GMs don't want to deal with Philly and agents don't want to send their clients to Philly to play.
A three to five year tank might work in games, but not in real life. It causes too many negative emotions that are seriously counterproductive to building a winning team in the NBA.
