I do think the committee used to give some weight to how teams did in their last 10 games. I'm not sure if they still do - I haven't heard any talk about that this year.
I think the issue most Nebraska fans have is they are putting a lot of weight on the more recent games and minimizing the earlier games. And I think that's a valid point. I just don't know if that's how the committee looks at it. If they're mainly considering the "body of work" as a whole, I don't think a lot of the arguments people are putting up for Nebraska mean as much. Not that we played terrible early in the year but we definitely weren't playing as well which is part of why our RPI is lower - because it's looking at the entire season. And, on the other side of the same coin, it's why people are talking an Oklahoma down more than the "experts" - because they played better earlier in the year and had some really big wins but lately have done poorly. But their overall "body of work" taken as a whole still have some impressive marks to it.
This part has bugged me a lot with Oklahoma. If you actually look at their resume, their best non conference wins rank like this:
1. @ Wichita State - really good road win
2. USC - they are on the bubble
3. Oregon - they won't make the tournament
4. Northwestern - they were terrible this year
They lost to Alabama and Arkansas in the non con.
They beat North Texas by 10, Nebraska beat them by 19
They beat UTSA by 12, Nebraska beat them by 10
They played UNO (RPI 281), Portland (RPI 285), and Northwestern State (RPI 342)
I get that their resume looks better than Nebraska, but it's basically a road win at Wichita State and a lot of meh...
(Edit: I'm not directing this at you Mav, it's all the talking heads that are in love with Oklahoma... I don't know how they can justify it)
