I agree with this completely... there have been too many times I have been online playing someone as the Cowboys and the contunously pick a Dime or Quarter package and the user will select Pacman Jones and simply burn my guards on the outside... I was able to somewhat counter this by using a 2 TE set and sending the 2nd TE in motion to the blitzing side and scrambling to the weak side.
But this should be analyzed... seems in Head Coach the same is "thought" to be true... I will check the success rate of many plays and they want me to use a quarter man defense with 2 deep to counter the 1st and 10 or say 2nd and like 4...
