It looks like maybe I need to work in play calling a little more for passing. For rushing, changes in formation will be pretty subtle when looking at pretty similar formations, but should be a little more pronounced when comparing something like a 4-4 against the Nickel. Also, a higher rated defensive line and LBs will be able to do more with less at the line. Much of the game plan settings, formation and defensive type, are going to play in more for TFL and short rushes. More long runs would come just because there are less tackles at the short range, but I think once a guy starts rushing at some point the defense is no longer affected by their defense call. Currently, it's once they get past short range. Likewise for passing, at some point the defense realizes it's a passing play regardless of call. I might adjust that to see if it affects the passing plays a little more. I might also have to see if I need to adjust the coverage on the passing play because I think that would suffer, at least those first few steps, if the defense called rush.
But again, you still have to look at match ups. If a team is way better than another team, or specific match ups are better, they are still likely to have the advantage even if they call the wrong play. Like they might not break through the line and tackle the runner for a loss, but once he starts trying to break through the line, the defense realize what he's doing and their superior talent let's them make the tackle attempt. So they might not be as dominate as if they called the run, but they are still pretty good.
Passing does have a few more complexities when looking at these types of disadvantages for wrong defense, so I'll have to review them.
