Pro Football Focus knows what it’s doing when it comes to football.

Sure, who is really an expert? But, if you put in the time and use data to support an opinion, at least it’s a credible one.

The team at Pro Football Focus put together its own ELO college football rating system and describes it as, “Like all ELO systems (including our version for the NFL), PFF ELO is an iterative system that updates each team’s rating after each game based on two things: how well they played against their opponent and how well they were expected to play against their opponent. The PFF ELO rating system measures the former using our unique offensive, defensive and special teams grades, while the latter is determined by the PFF ELO ratings leading up to the game and where the game is played.”

Following Week 1, the ELO system had new information to go by. And with that, a new top 5 has been released:

Alabama, Georgia, Clemson and Oklahoma are in there. No huge shocker. But at No. 2 is Wisconsin. That speaks to what this rating system in particular thinks about the Badgers.

The Preseason AP Poll had Wisconsin at No. 4 to open the season and after one week, dropped the team a spot to No. 5. The Badgers are supposed to be really good.

But, PFF’s ELO system thinks they belong in the national title game. Badger fans would surely be happy with that.
