This is what I found.
Out of 100 tries, the Celtics ended up with the 1st pick 29 times, the 2nd pick 21 times, the third pick 16 times, and the 4th pick 34 times.
At the 1 spot, we drafted Fultz 29 times in a row, or 100% of the time.
At the 2 spot, we drafted Fultz 12 times and Ball 9 times. This means we end up with Fultz 57% of the time even if we draft 2nd.
At the 3 spot, we drafted Jackson 15 times and Fultz 1 time (when the Lakers picked Ball first and the Suns took Jackson second). This means that, even at the third spot, we end up with Fultz 6% of the time.
At the 4 spot, we drafted Tatum 34 out of 34 times.It seems that ESPN has our big board as Fultz > Ball > Jackson > Tatum which is not surprising at all.
Feel free to join in the "Fun" here's a link to my raw spreadsheet. Next time I do this I'll track whether or not the Lakers lose their pick. I wish I'd done it from the start.
