The trends the last few years that have kept ISU from being consistently solid are not playing very strong defense, and having issues with blocking out for defensive rebounding.
I'm not quite sure how people keep thinking ISU is Final Four material, or are projecting things like 2-3 seeds before February, when these trends continue.
Those are the reasons that they're getting beat by OU right now.
Unless something drastically changes in the next 11 game minutes and the rest of these road games (plus some tougher games in Ames), ISU might be looking at 10-11 losses on the year. I would assume they make the tourney, but it's right back to the 8-10 seed range.
