I wish I could be so positive. I'd say we've got about a 30% chance of making it now, down from about a 80% chance had we won ('cause we'd have had tiebreakers with every good, non-OU team, plus we'd still be undefeated).
The truth is, ISU was an unfortunate team for us to lose to. Pretty much, we need to beat OU now, because otherwise, we won't own tiebreakers with either OU or ISU, and those will be the two teams playing for the conference championship yet again—unless of course ISU loses two more times, say...to OU and Texas. While that could happen, it's not exactly controlling our own destiny to need a Texas win over ISU. Last year, we were in the exact same situation, only to make the whole thing moot because we also lost to TCU (in addition to OU).
Interestingly, our remaining schedule is identical to ISU's, except we've got Kansas whereas they've got Texas. Again, we need Texas to beat ISU, and we can't afford to lose even 1 more game other than OU.
The good news: We finally got some decent offensive production, and our D, while not dominant like we needed, was still pretty good. And I'm not aware of any major injuries. That's a bigger deal than we like to let ourselves admit each week. It could be that if ISU does stumble in the next few weeks, it'll be due to them suffering injuries to some key players. For what it's worth, none of this matters if we just go undefeated from now on, and OU looks more beatable than in past years.
