FWIW, at first glance it appears Nebraska, Purdue & Minnesota may have the easiest schedule vs the East in 2019.
West vs East in 2019:
Nebraska plays OSU, Ind @ Maryland
Iowa plays @ Mich, PSU, Rutgers
Wisconsin plays Mich, MSU @ OSU
NW plays MSU, PSU @ Ind
Purdue plays @ PSU, Mary, Ind
Minn plays @ Rutgers, Mary, PSU
PSU can't play four West teams next year.
