Two things I will disagree with you on slightly,.....slightly.
First, I think (I would have to double check) I believe any loss outside of an RPI of 125 is considered by the committee as a bad loss. I don't recall where I read that, but I do recall picking up that little tidbit of info somewhere recently. IF I am right (always a big if) than only the SIU loss is considered "bad" as last I saw Tulsa was within the top 125, though I have not paid attention in the last two weeks so they may have fallen back below that threshold.
Second, it won't matter if we win out, and get to the tournament final and lose, we won't get an at large. We just don't have the resume. We are now 0-3 vs. Top 50 teams in the RPI with a SOS of well over 100, and we won't have the chance to improve that until the MVC tournament and if we then would beat the shockers the point would be moot as we would be an automatic qualifier. Put it simply the committee will look at us and say "didn't play too many tough teams and when they did, they lost them all".
We are all pro ISU, but if you look at our numbers against many other teams in a blind draw where they put the data up and say pick team a or b or c, the vast majority of us would not pick ISU to be a tournament team. We just don't have the resume. Nothing jumps off the page about our season that makes the committee take notice and put us in.
The at-large talk pretty much died last night around 10pm.
