What I've always wanted to see done is an objective analysis analyzing the success percentage among various picks.
You would start by defining different levels of success:
1) 5+ Pro Bowls
2) At least 1 Pro Bowl and X number of starts
3) X number of starts
You could find classifications for each position if you want and then have an objective grade say 1-4 for each player drafted. You would then look at the probability of reaching success at each pick and compare that to the Draft value chart used for trades.
So maybe you find that a #10 pick has a 8% chance of becoming a superstar and a #25 player has a 6% chance. So if you could trade down from 10 to 25 and acquire say a mid 2nd rounder that theoretically has a 3% chance of being a superstar then it would always make sense to trade down.
Instead of having a #10 pick with an 8% chance you have 2 players that together have a 9% chance of at least one of them becoming a superstar.
I wonder if the Phins would pay me to do the analysis?
