Right now we have no clue how the committee will use the new NET rankings. Many Iowa fans seem to think that being in the top 30 or so guarantees them spot in the field. But right now we just do not know.
If you look at Iowa's resume as of today, they have one very good win verses ISU, a couple of good wins against UCONN and Oregon, that are starting to look very average at best. Their SOS is at 68 as of today. In their five losses they were blown out in three of them and lost the other two by 5 and 6 points.
Iowa has work to do, to not end up like Nebraska last year, who I think finished tied for 3rd in the conference and went something like 13-5 and was left out.
