I don't have as much of a problem with the yardage results as the number of rushes, but this is also an issue with the number of rushes we are seeing with RBs out of any of the formations as well. I think the rush numbers are only off by a little and maybe slightly even more off with pass defense, but I think the rush numbers are getting there. I want to get the fatigue in to see how the numbers look then. I am taking into account the differences in defensive settings and the game planning effects on the results, which I think are all tending the right way and maybe only need a little tweaking. If a team is running QBs or WRs out of passing situations, the numbers shouldn't be super enhanced just because the defense is set up for pass, but the numbers should definitely reflect that its the wrong defense - then you factor in team match ups and I can definitely see these WRs getting some good rushing numbers. There's also some discrepancy in the generated upper class players and the lower class players that you can get some pretty big mismatches in talent alone.
The real question is how much should a team be able to get away with in GD with the pre-set game plans where in real life a team would be able to adjust after a couple drives. On one hand, I think a coach should be able to game plan and give his team a better chance, but on the other hand, I don't want people switching from one unlikely game plan to another and being successful just because they don't follow conventional football wisdom.
