I know play-action is a huge part of the ZBS, but it was a staple of the offense (therefore a focus of the defense)... Also, with all the boot action, it allowed the secondary to eliminate huge chunks of the field. Effective power running will cause safeties to react downhill to play action even if they are not assigned to the box... creating over the top opportunities from one sideline to the other.
All that is to say that I doubt the plan is a conservative one- just a physical one.
