Using Clustering to Develop a College Football Ranking System

Looking at the top 25 teams from last year, the first four are identical. Also, according to polls of the top 25 teams from last year, this algorithm classified 20 of those teams in its top 25. This may not seem good, but teams in the lower half of these rankings often drop out from week to week, while teams just outside the top 25 come in. ................
