“ Clemson has beaten 4 top 25 teams including #10 Auburn non conference.“
I believe that was from 2017. See link for the 2019 schedule.
I just heard a conversation on ESPN regarding how weak the ACC is that a defending National championship team that is undefeated and played no ranked teams might be left out because there may be 1 loss teams with a better resume this year.
Just for my thoughts on that topic. They will not be left out.

Texas A&M. Only ranked team played this year.
