I'm no mathematician, but if we finish 4th last, like we currently are, the most likely position we draft would be:
-5th
-3rd
-6th
-2nd
-1st
-7th
-4th
The only way we pick 4th (if we finish 28th, ahead of ARI/BUF/VAN) is if those 3 teams all win the lottery, keeping us at 4, otherwise a team behind us wins a top 3 selection, bumping us down to 5 or 6.
If you run the lottery 20 times on tankathon, you probably won't get us picking 4th at any point, it's mathematically unlikely.
EDIT: Just for fun, I ran the lottery until it resulted at us picking 4th, and it took me 28 tries.
