If teenagers aren't supposed to immediately contribute, then doesn't that increase what Tatum has done this season?
I am not going to fully analyze the trade at this point because it's way too early for that, but to just brush away Fultz not playing in his rookie year because rookies aren't supposed to be good seems like a bad take. Fultz should have probably been better than TJ McConnell this year. And TJ is getting 25 minutes a game for a team that should probably make the playoffs.
Also, comparing Fultz to Embiid and Simmons is flawed on many levels, but if Embiid or Simmons didn't get healthy, then the team would have future lottery picks to make up for it. If Fultz never learns how to shoot a basketball like he used to, then the team loses out on that pick, the future 1st that was given up, and the team is now good enough that it won't have a high pick to make up for missing on the 1st overall pick. The Simmons injury got the team in a position to get Fultz in the first place. The same cannot be said of Fultz not playing.
The recent video (I've only seen 2 videos in the last week and they only contained a total of 3 shots) still shows a hitch in his release. It also doesn't account for what happens if he is at the FT line or is lining up a 3 in a real game. Who knows what's going on his in head, but to use Nick Anderson as an example, the guy didn't want to get to the FT line after his struggles in the finals.
And I criticized the trade when it was made, but the trade is over and I am hoping for the best. Still, if a redraft was done today, where would Fultz be drafted? While it may not be fair to criticize the trade based on Fultz's struggles and he might go on to have a great career, I think you have to admit that Fultz has lost value as an asset since he was drafted. I guess you could make a case that Embiid lost value as an asset (especially when he missed a 2nd season), but the only reason he fell to the Sixers in the first place was because of the injury. The Sixers had to trade a valued asset to go get Fultz, which impacts this situation.
