Agreed, and that's the mind-blowing part for me. The apologists act as if Hinkie invented a brilliant, revolutionary method of rebuilding, when the plan of "getting really bad to get high draft picks" is as old as the draft itself. That's the first thing which comes to any GMs mind when he faces a rebuild, it's how every kid on the planet plays GM mode in NBA2K.
I think it's less that he "invented a revolutionary method of rebuilding" and more the strict adherence to a long term plan without regard for short term consequences.
It's the way everybody plays GM mode in NBA 2K because in the video game you're not beholden to the constraints of fan revenue, player morale, constant media criticism, or ownership expectations, and it's also really easy to take advantage of opposing "GMs" controlled by the AI to put yourself at the top of the draft virtually every year.
It was fascinating to see somebody actually try to put that kind of plan into action in real life, where all of those factors are actually in play and opposing teams are run by actual people -- mostly intelligent ones.
A lot of people, I think, respect that completely unsentimental approach to the incentives system in place in the NBA. ("Don't hate the player hate the game," basically)
To many others, that same disregard for the way things "should be done," including the perceived obligation to actually put a plausible product on the floor each night, was distasteful, even repugnant.
There are plenty of reasons why it didn't work out, and none of them are especially surprising. The plan has not yielded the kind of returns the Sixers no doubt hoped it would (i.e. they haven't become the Thunder yet) because they didn't have good luck in the lottery.
Despite that, I think it's far too soon to have judged "The Process" a failure because most rebuilds are going to take a lot more than three years to come to fruition, especially when the starting point is as bad as it was for the Sixers.
That there, actually, is probably the biggest disconnect here, and maybe the biggest reason "The Process" has been so polarizing.
Many regarded the "all out tank" strategy as one that was designed to guarantee instant gratification -- multiple top 3 or 4 picks in a row. What can go wrong?
I think it's actually the opposite. Even an all-out tank can't guarantee that over a three year period you're going to "win" the draft and end up with multiple All-Star prospects. But going that route is probably the easiest way to ensure that after five or six years of hanging out in the lottery, you will have such a mountain of assets that you can build the team pretty much any way you want after that.
Some teams hang around in lottery land for a decade or more and end up none the better for it. See: Kings.
