Curious to know exactly how you guys playtesters go about testing individual ratings #'s. It doesnt seem like this is really tested very well, which in turn leads to things such as the d line having problems pressuring qbs, smaller players running over bigger players, etc. Here's my 2 cents for ya. Take two player models, put em on the field and tweak numbers as you control these players until you observe the correct outcome.
The way I'm visualizing this in my mind it doesnt seem like it would even take much time to do. I know 2010 is probably already in development, maybe you guys can pull the testers coat right now and have em jump on it, so by July next year it should be perfect.
