Whatever rating system or advanced stat is consulted, these two unbeaten teams are among the country’s best. Here’s a look at a few.

FEI represents the per-possession scoring advantage a team is expected to have on a neutral field against an average opponent. Offense (OFEI) and defense (DFEI) represent the per-possession scoring advantages for each unit against an average opponent unit.

• Clemson: 3rd in FEI (1.14), 6th in OFEI (1.27), 2nd in DFEI (1.35)

• Notre Dame: 6th in FEI (.86), 8th in OFEI (1.06), 12th in DFEI (.77)

The FPI is a predictive model that is rooted in projecting success (or lack thereof) over the course of the season based on 10,000 simulations using FPI, existing results and remaining schedule. The number itself represents how far above average a team is.

Clemson: 3rd (26.8), 36.7 chance of winning out

Created by ESPN’s Bill Connelly, SP+ is a tempo- and opponent-adjusted efficiency measure. It’s not a resume ranking, but rather a measure of what’s most sustainable and predictable in football.

Clemson: 4th overall (28.1), 6th offensive (41.0), 10th defense (17.0)

Notre Dame: 7th overall (13.6), 16th offense (36.6), 8th defense (15.7)

PFF rates Notre Dame as the No. 14 offense (an overall grade of 85.5) and Clemson as the No. 2 defense (93.5). the Irish’s highest-graded offensive category is run blocking (89.0), while Clemson’s highest-graded defensive unit is its run defense (91.8).

Takeaways

• Like Notre Dame’s offense and Clemson’s defense, the Tigers can run the ball and the Irish can stop the run. No individual player has topped 100 rushing yards against Notre Dame’s defense this year.
