1. Ja Morant - idk how anyone could possibly argue anything else. Philly jumped from 13 to 1 on a real life owed pick swap with Brooklyn, and they already had won like 65 games or something that year with Embiid and Butler and Harris and Simmons, if Philly would’ve went with Zion or Barrett or even Culver, Philly has an untouchable dynasty, the fact they had that embarrassment or riches and got 0 titles and the biggest TO machine and tank commander ever, I’d unequivocally the worst #1 pick ever
2. Gabriel Deck - the fact he got taken over Jones was bad on draft night, it made no sense to anyone. Letting college performance hold that much weight was a tough lesson for Utah, but Jones going on to being a top ~5 player in league history and Deck being a mega bust was just a pound of salt in the wound. Cool story when he joined Seattle though and won a title as Jones’ backup.
3. Jalen Green - he was like the 6th best spec at best on draft night so he never even should’ve been the top pick, idk how Catdude landed on him, his build was so bad though. He was like a terrible inside scorer and rebounder but he was a wing with high handles and shitty shooting, he wasn’t even eligible to play PG either despite his playmaking being the only semi valuable thing about him. And to address air’s point above, I ended up trading dead Kawhi’s max for him just so I could rookie option cut his $10M salary and get under HC. That was a salary cap maneuver not a value move. #1 pick that didn’t even last his rookie contract is almost unheard of.
4. Dave Bing - I remember being one of the people really championing Mike Moser as the #1 pick in this draft, and he went on the be a really good player, so that definitely stings for Charlotte. I honestly think Bing was a bottom 5-10 player in the league in terms of guys that got consistent minutes during his tenure, he really didn’t bring any value to the court whatsoever, he was a minus across the board forsure, and the pick never even made sense for the way Brack was going to use him either, he was always just going to show horn him into a very fast outside offense and have him chuck when he was an inside scoring play maker with bad handles, so just an all-around unmitigated disaster.
5. June Mar Fajardo - He should’ve been really good and he was the right pick at the time, just an unfortunate mega bust situation, the only thing keeping him from being higher on this list is he was actually a pretty valuable rebounding specialist that could provide valuable minutes at an affordable price later on in his career
