When factoring in all of who he ranks (and like NU, doesn't rank) his predictions are really, really poor. I am not convinced that he actually ranked based upon what he thought the final polls would look like but rather on how his poll would elicit response and sell. In other words, this smacks of a marketing ploy rather than a legit set of predictions.
Regarding the Huskers, their schedule is too weak not to end up with 9-10 wins (even if NU is no better than they were last year) --- and that should land them ranked at seasons end (at least 10 would). With this schedule, not ending up ranked would be epic failure of the highest order --- and I'd think is really unlikely --- the Huskers will finish ranked.
