I like the computer models. I think they are useful. Same for yours, Medina.
Your version looks like it may struggle with the strenght of schedule: Oregon played a weaker schedule than Ohio State, but it still won all of its games. They also don't do a good job of capturing the teams that are better or worse in close games. Sometimes it's just luck, but when you get a consistent set of results, it starts to suggest that some teams handle the stress of close games better. That is a behavior that can be learned/coached, so when you have a team that consistently wins or consistently loses those close games, I think it's fair to take it out of the luck category.
Strength of schedule shouldn't be an issue because my model doesn't compare you to the teams you played, it compares you to the other teams that your opponents played.
It should only be an issue if your opponents played a particularly strong or particularly weak schedule.
Examples:
Purdue had a REALLY tough schedule. They were the only team in the league to play all of the top-4 and they also played Illinois which has an argument for #5. Consequently, you had to really beat the snot out of them to get a decent rating:
- IU beat them by 66
- UWisc beat them by 46
- tOSU beat them by 45
- PSU beat them by 29
- Ore beat them by 28
- UNL beat them by 18.
Nebraska's 18 point win over Purdue would probably have been a lot better IF Purdue hadn't also played IU, UWisc, tOSU, PSU, and Oregon.
Conversely, Rutgers had a very soft schedule. They were the only team in the league to miss all of the top-4. So, against the Scarlet Knights:
- UWisc beat them by 35
- USC beat them by 22
- IL beat them by 7 (Piscataway)
- UNL beat them by 7 (Lincoln)
- UCLA beat them by 3
I don't think that IL and UNL would have been top-4 against them if they had played Oregon and Penn State.
In theory that could be somewhat unbalanced but I am taking nine different comparisons so it should even out because there are a LOT of datapoints in there.
This method definitely doesn't do a good job with teams that just "find a way to win/lose". I think most objective measures don't.
