I've heard a lot of people talk about how bad the Big 12 is this year and by the metrics that isn't quite correct. However, this is similar to the yearly discussions during basketball season about the league when it ranks #1 in the metrics; there are a lot of competitive/solid teams, but perhaps not a dominant, playoff caliber team. The only dreadful team in the league is KU, everyone else is basically in the top 50 of the metrics. Oh, and the new additions are all pretty good too.
F+ combines the FEI and SP+ (Fremeau's and Connelly's). OFF F+ and DEF F+ combine offense and defensive rankings, then the FEI and SP+ are at the end. Rankings are color scaled from green (good) to red (bad). Neither ranking includes games against FCS teams.
