Using the Felis System(tm), I note that the bottom of the conference in 2016 lost all games played against the eventual Tournament champion where as the bottom of the conference in 2017 has not lost a single game against the eventual Tournament champion.
In addition, the bottom of 2016 lost two games the opening night of the Big Ten tournament whereas the entirety of the bottom of 2017 have yet to lose a single game in the big Ten tournament this year.
It is therefore incontrovertible fact, using the Felis System (tm), that this year's bottom of the conference is much stronger than it was last year.
