If you analyze Clemson’s opponents there are some stats that will come up if you dig deep enough.
For instance, Clemson is ranked #18 in scoring defense which is pretty impressive, that is unless you dig a little deeper. If you average out their opponents offensive scoring rankings (and eliminate Wofford) you will see that that average comes out to 63.92. So in effect on average they faced offenses that ranked #64 out of 127. That includes facing #110 S. Carolina, #120 W Forest, and #121 B College. The highest ranked offense they faced was N Carolina who scored 37 points against the Tigers. NC State scored 41 against them with their #38 ranked offense.
Just for the record on average OU faced teams who averaged #47 but they faced the #1, #2, #8, and #9 teams in scoring offense.
