They have an UBER easy schedule and a team full of seniors, especially on defense.
It couldn't have BEEN a better year for a team to go through a coaching change. They'll win enough games to go to a respectable bowl, it would be difficult not to with that schedule.
If you didn't think it was possible, their 2014 schedule could actually be easier than this year's, again missing Michigan, Ohio State, Michigan State. It will be a while before Wisky is anything more or less than a mid-level BT team, behind the likes of Michigan, Nebraska, and Ohio State (and before too long again Penn State), but ahead of several others. At this point, I'm not sure I would put them, in their current state today, much ahead of Northwestern who is definitely trending upwards.
