Pass Defense & Run Defense Questions

[King Crimson]

Love this game, been playing it since I was a beta tester! :- D

I want to set Custom Options so that Run Offense plays are a Rookie four yard match, and Pass Offense plays are a Veteran 8 yard match. I'm trying to make run plays a bit more effective than pass plays because IMHO it's much easier overall to gain yardage by passing. So I'm trying to level the yardage gained between both the Offense and Defense for teams.

What I'm confused about are the Run Defense and Pass Defense settings. Does a team's Run Defense of 35, or 30, or 25 yard max gain benefit a team's offense or defense?

I have the same question with Pass Defense. Does a team's Pass Defense of 35, or 30, or 25 max gain benefit the game's offense or defense?
