Computer models use a combination of game outcome vs SOS. Game outcome is usually a combination of winning percentage and MOV. But sometimes it is just winning percentage. In winning perentage BYU is tied for #1 with 9 other teams. In MOV, rankings vary but my ranking on MOV with a diminishing principle has BYU at #5. BYU vs Utah in MOV is not that dramatic to make a major difference. The main issue is the SOS. |

I reproduced that Sagarin predictor without using an empirical bayes adjustment and there are some differences. Also it does look like the adjustment is helping BYU a bit. BYU is 17th in the non-adjusted MOV model and 11th with the empirical Bayes adjustment. My calculation of the Sagarin MOV (unadjusted) rating could be slightly off, but I can usually almost exactly reproduce Sagarin since he uses raw MOV in his predictor model (his predictor model is pretty trivial to reverse engineer). Below should be Sagarin MOV top 25 without the Bayesian adjustment: Code:

MOV used to be in the BCS computers. They took it out SU, not for ethics or sportsmanship, but because they believed MOV had too much weight since it is heavily considered in the human polls which have 2/3 weight.

That is atrocious rationale. The sole purpose of any poll, computer or human, should be to project who would be expected to win in a given matchup. You cannot credibly model future outcomes of football games without MOV in that model.

I don't think this is correct. I think they took it out for ethics reasons.

please, is this a joke? Navy and Toledo must be national championship contenders. There you go again proving you don't know jack squat about sports.

Couldn't a system that uses MOV add some sort of "score cap" feature? Meaning that Arizona's 70-0 win over Idaho doesn't count as anything more than a 21-0 win, but Auburn's 3-2 win over Miss State still only counts as a 1-point victory...
