If we finish bottom 4, which is realistic if we sell off Siakam, OG etc. I listed the actual odds in a follow-on post. Teams tank all the time but doing so with this sort of pick protection where you are targeting a specific loss record is a different level of tanking. Then also factor in the terrible culture that would be in place while this is all going on. Then, you have to pull this off 3 seasons in a row to avoid the pick going to the Spurs.
If you finish 5th or 6th worse which isn't easy to do in the first place with so many tanking teams, you can easily find yourself picking 7th or 8th and losing the pick. To lock in a Top 6 pick, you need to finish in the bottom 3 because there's still the lottery component to it.
