The 1st ball drawn will decide the first pick in the rookie draft, the 2nd ball the second pick, and the 3rd ball the third pick. Only the first 3 picks are decided by the lottery.
If 2 of the first 3 balls fall into the same grouping, the duplicate ball will be ignored and the next ball that falls into a new grouping will be taken in its stead.
After the top 3 positions are decided, the remaining teams will draft in reverse order of regular season final standings (after tiebreaks are applied).
So yes, you got the first pick and I have second.
