Notre Dame sucks. They are always ranked high just because tons of people like them.
You can say that about many teams. ND is not top ten material. But they have a realistic chance of going 8-4 or 9-3 with their schedule, 10-2 if they get lucky. 5-7 or worse is also a possibility, but I like to hope they'll do better than that.
I would not be surprised to see ND in the top 25 at the end of the year.
