re: LSUMATT - can you explain how we dropped in the BCS ranks?

dono if anybody has mentioned it but it could possibly be because Boise State played its 12th game this weekend and won while we were off?

Ok I dont get it.. Colley Matrix states that they DO NOT USE FCS data in his poll.

Do mind sharing where you got the quote from? It may be outdated. Colley used to not use FCS data, but after 2006 decided to start to include them. Though the way the FCS data is included is not the same way that the FBS data is included.




-------------------
Which leads me to my question to Matt,

Matt, since you seem to understand the math behind Colley better than I do...

I know that Colley ranks all of the FCS teams based on the same methodology. After he ranks them, he puts them in groups them and puts them in the FBS polls as "FCS Group 1/2/3, etc."

My questions are:

When an FBS team beats an FCS team does it get rated vs the FCS team's individual ranking or does it get rated against the "FCS Group" rating?

Are these groupings static?

If not, is it possible, that the App St. win over West. Illinois, shuffled the groupings around and ultimately changed everyones SOS and ratings against FCS teams they played?

It gets rated against the "group". Basically Colley lumps teams into groups and that group collectively becomes an FBS team. The best 10 teams in FCS might make group 1 and the next 12 teams makeup group 2. Group 1 "ends" when enough teams have played 12 games (the number of games played by most FBS teams).

no, not at all. They change each week as the FCS rankings change.

That is a really good point and could be it (I would have to look into it). I would have thought those two were already in group 1 (it was a championship game right), but if not yes that could be it.

This whole debacle has got me re-interested in all of this. I am usually a bit sloppy when I re-do the Colley matrix myself, but may see if I can re-create the mistake and see what really went wrong

What I don't understand is how the only team affected was lsu. Shouldn't all the common opponents of the teams in the forgotten game have similar changes?

---

A lot of teams numerical rating were affected by this, but LSU was one of the only a few teams that like a 0.001 pt change dropped them in the Colley Standings. And LSU was the ONLY team that also had a very small lead in the overall BCS so that the change in Colley affected the BCS standings as well.
