Last year 99% of participants would have been out at pick 4.
This would be the most complicated of equations because you would have to assign weights to each player(top 60 players?) and their likelihood of going in each position before you even start the math. and those are all arbitrary based on whose assigning those. An equal weighted permutation between all available draftees would be wildly innacurate.
look through previous contests would be the best way to get this data.
in order
S(depth) (this is only first because I want Chinn, if not available this can be later)
EDGE
RB(not depth, you need 2 in this league, and there's injuries)
OL(depth)
P
LB
