Based on the current z-scores for all teams on the B1G team schedules for 2016, only considering games against FBS teams (such that there's no penalty for playing lower division teams), and applying no adjustment for home/away...here's the order I came up with - the numbers given are the average z-scores for the 2015 teams' stats:
Wisconsin 0.255
Northwestern 0.217
Rutgers 0.213
Illinois 0.203
Ohio State 0.197
Michigan State 0.167
Purdue 0.088
Penn State 0.073
Nebraska -0.015
Maryland -0.073
Michigan -0.099
Iowa -0.119
Indiana -0.126
Minnesota -0.131
Maryland only has ten games scheduled against FBS teams so far - I think they need to add another game yet (as they're only at 11 when you count Howard). I think it bears mentioning that Michigan's 2016 out-of-conference slate features three of the worst-performing teams of this season in Hawai'i, UCF, and Colorado...though the Buffaloes' numbers are respectable next to those of the Rainbow Warriors and Golden Knights.
p.s. - A z-score close to zero, like Nebraska's, means the average 2015 z-score of all the teams on Nebraska's 2016 schedule is...pretty much average.
