guys. They all (or essentially all, I've never seen any to the contrary) weigh games completely independent of any conference affiliation or anything like that. The ones that provide pre-season or early season rankings will have some sort of formula that they use to weigh teams at the outset, but that decreases over time until there is enough data to create a "grid" that is completely neutral and blind to any conference or historical bias. The grids basically analyze how every team has done against other teams to several degrees. This is the general structure. Different models weigh margin of victory differently and vary with how much they weigh downstream results (in other words, how much they weigh opponents' results, opponents' opponents' results, opponents' opponents' opponents' results, and so on). Once the grid is in place there is no bias whatsoever and it is completely blind as to conference affiliation, team perception, or anything like that.
