Many have pointed out it's early in the process and they are correct. I'd also expect some commitments coming soon that will boost the ranking. But, if you look at the offer list and who Notre Dame leads for, it's pretty dire at the moment. It also seems they are going to miss on a few prospects who they were leading for. Kenyatta Watkins, Chez Melusi, Nana Mensah all looked like Notre Dame guys a month ago, Melusi is now gone and I'd be surprised if they got the other two.
The state of play right now shows Notre Dame's ceiling this year around #15 nationally. They need running backs and can't find traction anywhere. It's becoming a concern.
