Yabusele is perhaps the worst pick since James Young.
I think you have to go all the way back to Albert K. Brown in 2001 to find a worse Celtics pick than Yabu.
Fab melo - rip and jajuan Johnson can be argued were worse picks given that they played in the ncaa tournament
I have posted before that Danny has 4 of the top 10 worst picks in the last 15 years in the 15-30 range
Im pretty sure there were a lot worse picks, esp in the 20-30 range.
Here are some:

#16 Chicago Justin Patton
#28 LAL Tony Bradley
2016
#25 LAC Brice Johnson
#26 Sixers Forkan Korkmaz
2015
#17 Milwaukee Rashad Caught

That's just 2010-2017. I didn't do 2018 because those still need to be evaluated more. But that's 27 picks only in the last 10 years that can be argued are every bit as bad as some of Ainge's picks in the #16-30 range.
Some are made even worse by being near a great player that could have been selected instead.
Tremendously bad picks happen to everyone and are very common. Even teams that normally draft well make mistakes. San Antonio have selected two guys that have never even played for them yet and might never.
