IMHO if they handle their business against the dregs and beat Arizona they should still be in play for a 2. Alabama, Florida, and A&M have multiple tough games remaining. Tennessee irks me because they have a similar profile to ISU yet, despite ISU's recent offensive woes, are even worse on that side of the ball. Being the best defensive team certainly helps, but maybe they'll drop one or two they shouldn't. You probably aren't hopping Purdue. That leaves Houston (Auburn and Duke are basically locks), and fair or unfair I think the committee is going to put a lot of stock into that game even though ISU only plays them once
