NBA TRADE TALK: TDL over

[HIMAV]

I know it's not really comparing apples to apples, but I do feel it its still a fair question (maybe equivalent to comparing apples to peaches?):

Could the Ben Simmons' mental shooting issue have a similar result to the other #1 former Philly pick Markelle Fultz? Markelle also left the 76ers as having a mentally broken shot, but I think all agree he did improve with Orlando (though him tearing his ACL was an extreme set back sadly). I already admit that Fultz is still not a three point sniper with the Magic, but he was a way better Free Throw taker and overall better and more confident shooter. Could Ben Simmons make similar gains (if not more) by getting out of apparently toxic (at least for him) Philadelphia? 

For Reference on Fultz (ORL 19/20 really was his only full season):
18/19 PHI: 19 G; .432 eFG%; .419 FG% / 8.2 FGA; .286 3P% / 0.7 3PA; .432 2P% / 7.4 2PA; .568 FT% / 1.9 FTA        
19/20 ORL: 72 G; .488 eFG%; .465 FG% / 10.7 FGA; .267 3P% / 1.9 3PA; .488 2P% / 8.8 2PA; .730 FT% / 2.2 FTA
