I've been saying that for years. I love the Harbin system. It's not great and could use a few tweaks but it works pretty good. It penalizes an easy schedule and rewards taking gambles for playing tough teams. I've actually been translating the formula to use for college football. The biggest thing is how to decide on divisions. The 2 best formulas that I've had. One considers the power 5 conferences and ND as division 1 schools, the AAC and MWC are division 2, and CUSA, Sun Belt, and MAC are division 3. Then FCS teams as division 5. Then the other is based off the computer composite rankings. With teams 1-15 as D1, 16-40 are D2, 41-80 are D3, and 80-130 are D4. In both of them the top 4 are always Clemson, ND, Bama, and Ohio State. And Oklahoma 5th and Georgia 6th. The only difference is that ND is 1st in difference being the conferences. And Clemson is 1st when based on rankings.
