I know my breakdown is a little hard to understand but I will try to give you a better explanation of how it works.
For the Passing and Rushing Sliders you are going to be using
NFL Team Defensive stats to determine them and for the Pass D and Rush D you are going to be using
NFL Team Offensive stats.
Okay now take Pass Blocking as an example. What I do is go to ESPN.com and go to NFL stats and I go to Team stats not player stats. I click on Team Defense Passing, when this comes up I click on Sacks. This will now list the defenses sack totals from best "most" to worst "least" amount of sacks.
Now I usually copy this over into excel to make it easier but the question is how you rank them. So what I do is I give the 2 teams with the highest sack totals a slider setting of 30. Then the next 3 teams get a slider setting of 35, the next 3 teams a setting of 40, the next 3 a setting of 45 and so on till I get to the last 3 teams and give them a slider setting of 80.
As an example of what this does in game wise:
Pittsburgh and Philadelphia have the highest sack totals in the NFL, so they get slider settings of 30. So now when you are playing against one of these two teams your pass blocking slider will be at 30 and this will allow them to bring much more heat on you then when you are playing say Cleveland or Cincy which have the least amount of sacks in the NFL and have slider settings of 80.
I hope this makes it easier to understand now, if not let me know and I can go into a little more if you need me to. I have made 2 changes to which stat categories I use for a couple of slider settings. I forgot to update my breakdown page with it though they are the following. For (Passing) QB Accuracy and (Pass D) Reaction Time I use QB Rating for both instead of QB Comp%.
