their highest quality win is over 4-3 Virginia, who also happens to be the only team they've beaten who doesn't have a "losing" record.
We also currently have one common opponent with them (Stanford) who they beat 40-14 while scoring two TDs in the 4th quarter to get to 40, with their starters still playing the 4th quarter to do it.
By comparison, we were up 42-7 at the end of the 3rd quarter and played 2nd, 3rd, 4th, 5th string the entire 4th quarter and won 49-7.
So in regards to Clemson specifically, I call bullshit to your calling bullshit.
