In part one, we looked at the undefeated and one-loss BCS conference football teams and compared the win percentages of their opponents so far to estimate strength of schedule. However, we came up with some results that just didn’t look right. I mean, Texas Tech at no. 1, Oklahoma at no. 5 — ahead of both Alabama and Oregon. What’s wrong here?
If you looked carefully, you may have detected the problem already — we are giving Texas Tech and Oklahoma credit for opponents they lost to! Why should the Red Raiders be able to count Oklahoma’s five wins if they weren’t able to beat the Sooners head-to-head? Why should the Sooners take credit for Kansas State‘s 7-0 record?
So we need another table, this time only showing winning percentage of the opponents each teams actually beat.
That’s better; at least an unbeaten team (Florida) is back on top, though the pesky Red Raiders are still hanging out in second place. Alabama and Oregon move in front of Oklahoma in this list as well, which is intuitive. Louisville remains at the bottom — the Cardinals haven’t lost, but they haven’t really beaten anybody either. Ohio State and Kansas State both move in front of Cincinnati, since the Bearcats are not allowed to count Toledo‘s seven wins.
