Thanks for the lesson, you know they also have splits, double teams, cross blocking, traps, etc...
I blocked for 4 different thousand yard backs in college, and two before that in high school.
You can get as technical (or as Madden) as you want to get, real football is still a game of eleven guys that all have assignments and have to execute. Fronts, motions, whatever. It comes down to at the snap of the ball if your asisgned guy is owning you, you're not going to run the ball very effectively in your area.
Again, play calling had nothing to do with giving up hurries or sacks against LSU - that was an underperforming O-Line and coaching, that never adjusted.
