had a "BCS" specific ranking that took out Margin of Victory in its calculations (because the BCS wouldn't allow MOV to be included to keep people from running up the score to improve computer rankings). But you could still calculate a close approximation using comparable polls.
I will say, however, with the AP Poll/Harris Poll and Coaches Poll being 2/3 of the ranking metric, the BCS rankings usually ended up being pretty close to poll rankings most weeks.
