The point per Hinkie was to put the team in the best possible position to compete for championships, by quite simply playing the best possible odds.
If the Sixers never win a title, but essentially have a decade like the Mavs directly preceding the title in 2011, the Bucks in the 80's, or the Hawks decade with Horford, I'd think the Process would be deemed a raging success, and frankly it looks like the Sixers are set up to have that sort of run. Making the playoffs every year, winning playoff series a lot of years, and with a couple of deep runs is very hard, and it shouldn't be discredited just because they weren't the 1 team to win a title in any season.
