Hopefully, there will be some additional clarification as to determining what "targeting" is now meant to be. Previously, a "Cheap Shot", Unnecessary Roughness and even "Head to Head" seemed a lot clearer to understand, and respond to. Personally, I doubt the human eye is capable, nor the intent of the rule makers was to call these plays down to the subjective level of a gnat's eyelash in determine responsibility for moving contact when equal efforts are traveling in opposite directions.
Strange, but despite all the technological advances "Replay" has brought to the table, there doesn't seem to be much, if any, change in the immediate conclusions and opinions instantly created, regardless of what any amount of replay detail may provide.
