Hinkie had 2 picks in the Giannis draft. Almost all his picks at the top of the draft sucked. His strategy was right he just sucked at selecting the players.
Ainge was much better at selecting talent. The two Jays speak for themselves, Philly could of had both.
Hinkie only had 3 drafts and the first he was hired a month before the draft. He made a draft day trade to take Noel at 6. Noel was widely regarded as the best player in the draft, but the knee injury he suffered in college scared the top 5 drafting teams away from him, which is why Hinkie moved in to acquire the pick for Holiday. In the Noel trade, the Sixers also picked up a future 1st round pick, which became the 10th pick in 2014. with the Sixers own pick at 11 in 2013, Hinkie selected the guy that would win rookie of the year. He almost immediately knew he wasn't worth the investment and traded him for a future pick (it ended up being the 10th pick in 2018 - Mikal Bridges). In the 2014 draft, with the Sixers own pick Hinkie took Embiid at 3 (again widely regarded as the best player in the draft but the injury in college caused him to drop). Instead of drafting Saric at 10 (the Pelicans pick he had just acquired), Hinkie traded the 10th pick for the 12th pick and then basically got their future pick back from the Kings (that would be the 5th pick in 2017 - De'Aaron Fox - a masterful trade by Hinkie actually got the Sixers swap rights with the Kings, which is how they ended up with the 3rd pick that was traded to Boston for the 1st pick) and then took Saric at 12.
It was the last draft i.e. 2015, that Hinkie had that did not work, but the Lakers f-d him by taking Russell. He either had to take a guy who refused to visit Philly and didn't want to be there in Porzingis, a non-center that clearly shouldn't have gone 3rd from a talent standpoint (hezonja, mudiay, johnson, winslow (though ainge may disagree with that one)) , or suck it up and take b.p.a. i.e Jahlil Okafor. He obviously took Okafor, which in and of itself wasn't as bad as it looked because Embiid got hurt again and missed that entire year. The pick by itself wasn't the real problem, it was not trading Okafor when his value was at its highest, but Hinkie only had 1 trade deadline to do that before he was gone (and he probably wasn't in full control because Colangelo had been brought in well before the trade deadline). It was not trading Okafor when they should have that really doomed that pick and the value. I mean Ainge was heavily rumored to be interested in Okafor and allegedly offered the 2016 Nets pick at the deadline that first year (Hinkie was still theoretically in charge at that point, but Colangelo had already been brought in and probably was the guy that backed out of that deal). Boston looks a heck of a lot different with Okafor instead of Brown.
