The suggestion has been raised that that strength of schedule waters down Indiana's championship push, but it's actually not at all uncommon. Wisconsin, for example, played the Big Ten's easiest schedule last season, when the Badgers won the conference outright.
In fact, since 2002, of the 11 outright Big Ten champions, only three -- 2007 Ohio State, 2013 Indiana and 2014 Michigan -- have finished better than 10th in the Big Ten in conference SoS*. Only one of those three, IU three years ago, finished in the top half of the conference, and even then, only barely, at sixth.
