Notre Dame needs to invoke the mercy rule in order to prevent further embarrassment at the hands of the best team of the most superior conference in all of college football. Alabama is stomping a mudhole in that ass and walking it dry.
ND secondary can't even begin to keep up with these Bama WRs. So not only are they getting owned on the line of scrimmage, receivers are wide open every play. Dominating the line does have a lot of effect on guys getting open of course, but this is also just a speed issue.
