Notre Dame's secondary showed off its depth against Louisville, but the Irish need to make some improvements to get into the CFP.

Notre Dame is 3-1. Notre Dame opened the season with a 23-13 victory over Texas A&M in College State, Texas, before falling in its home opener to Mid-American Conference school Northern Illinois, 16-14, in a stunner for the Irish. The Irish bounced back with a 66-7 victory at Purdue and then dispatched Miami (Ohio), 28-3, last weekend at home.

Notre Dame got revenge on Louisville in a hard-fought battle in South Bend Saturday afternoon. This game was not pretty, it was not a work of art, it will not be remembered as some instant classic, but it was a critically important game for Freeman and Notre Dame.
