The way I produce top 25 is halfway modeled after the CFP Committee rankings. It's a combination of power and resumes, this early in the season the committee tends to lean more on eye-test than resume. I end up matching them closer towards the end of the season. Indiana sits on top for now, but their season is backloaded and I'm unconvinced their defense will actually hold all season. The same can be said for Miami. Oregon is the only team to weather a top 50 schedule thus far, but it's not exactly downhill for them yet. Notre Dame has the easiest path, but I don't think they get in with another loss.
Playoff and conference projections. Texas still sits on top of the SEC, but not by much and it's the most wide-open conference. Model currently thinks it's Texas vs LSU in Atlanta, and those two plus Tennessee all have good position to make the playoffs. A&M and LSU this weekend likely shakes this up and determines which other team is in the driver seat. Georgia is the only top 10 team looking in from the outside, and that is mostly due to their schedule. Army and Navy are the top 2 G5 teams right now, and I think that's awesome.
As far as projecting Texas, we are pretty equally likely to drop another as win out:
