Hi James:
Sure. It makes sense to more preparation where our weaker areas might be. Sometimes a teacher may not be awrae they have a need (blind spot) so until that's identified, the weakness will remain. Being open to opposing viewpoints, peer review, even sitting in another's class for a time can open the eyes of someone who is blind to one particular area. Unless they see it and they are willing change, it won't be realized.
