As of today, 12/3, if the season ended now we would have the following picks:
The Celtics currently have the 9th worst record.
Brooklyn has the 6th worst record.
Atlanta has the 16th worst record.
Atlanta has the rights to the Net's pick so we would have their pick instead of the Nets.
Four teams in the west (Lakers, Suns, Grizzlies & Pelicans) have better records than Atlanta (16th worse) but by virtue of the fact that they would all be out of the playoffs if the season ended today, they ALL slide into the lottery, and Atlanta slides down to #20.
As to our own pick:
The 9th worst record gives us 17 lottery balls and would give us the following odds on various picks:
1st .017
2nd .020
3rd .024
9th .813
10th .122
11th .004
12th .000 (very tiny)
So, basically, we'd have a 6.1% chance of a top-3 pick, an 81.3% chance of the 9th pick and a 12.6% chance of a worse pick.
We would have no chance at the 4th-8th picks.
So we would most likely pick #9 and #20 if the season ended today.
