Yeah but exactly how well has that worked out for the Sixers? Cutting back on playing time for their actual good young players has stunted their growth and while Hinkie did a great job of accumulating more draft picks than he could possibly use, the Sixers desire to keep the tank rolling by drafting dudes who'll require time coming off injury has resulted in their roster being full of dudes who have wound up to be injury prone. I feel like people fall in love with the whole idea of having high draft picks without considering external circumstances that have much more bearing on the success of a franchise. I mean, while you gotta admire the moxie to acquire several first round picks a year, the Sixers have been doing that by continually cycling through any of their young players who even begin to look like viable NBA rotation guys (KJ McDaniels, MCW, Jerami Grant, Nerlens Noel) in favor of future picks which they'll use on more young players who they can then trade for even more draft picks to perpetuate the cycle. Since 2013, the Sixers have picked 1st overall once (Ben Simmons) 3rd two times (Embiid and Okafor), 6th once (Nerlens), 11th once (MCW), and 12th once (Saric). Of these players, two have since been traded away for more future assets (Noel and MCW), one spent several years overseas before coming to the NBA and becoming the presumed ROY (Saric), two are perpetually injured potential franchise players (Embiid and Simmons), and one is Jahlil Okafor. Considering how much effort the Sixers put into sucking over the years, its debatable how much of a return their getting on their investment.
Dallas has a lot more talent than us? Dirk is a bag of bones at this point. Wes is one-legged. I suppose Harrison Barnes is a borderline all-star reserve. Seth is producing at Buddy Hield levels so huzzah I guess. Nerlens Noel is a serviceable defender/rim-runner but he's nothing to write home about. Maybe more talent than the Kings but not by "a lot".
And you should watch the T-Wolves before claiming they're on the tank train. Actually don't. They're just bad.
