Entering 2018, Here is a look at each school’s regular season cross-division mark since the East-West split in 2014:
West
Wisconsin: 8-2
Iowa: 6-4
Nebraska: 6-4
Northwestern: 6-4
Minnesota: 3-7
Illinois: 3-7
Purdue: 1-9
OVERALL 33-37
EAST
Ohio State: 9-1
Michigan: 7-3
Penn State: 7-3
Michigan State: 6-4
Indiana: 4-6
Maryland: 4-6
Rutgers: 2-8
OVERALL 37-33
So overall that actually is pretty close. But when you look at CCG it's a little more lopsided
West
Wisconsin: 0-3
Iowa: 0-1
Overall 0-4
EAST
Ohio State: 2-0
Penn State: 1-0
Michigan State: 1-0
Overall 4-0
I believe the West is suffering from a perception problem because it has not won any CCG yet. Until they start winning some CCG, the east is going to be perceived as better regardless of what the overall records are.
Also it should be noted that 2017 was a good year for the east. All of the Big 4 schools had good teams in 2017, but that is actually rare for all 4 teams to be so good in 1 year. 2016 is great example of a more typical year where MSU was down that year. In earlier years Mich and PSU were down. The only school that does not go through down cycles seems to be OSU.
It is still early in 2018, but the West clearly is off to a terrible start. We will know more after Wisc plays Mich and PSU and Iowa plays PSU and MD. Nebraska is hopeless and a big part of the problem in the west being down in 2017 & 2018.
One final note. How in the world is Iowa 2-0 against OSU and Mich and only 4-4 against the rest of east since the east-west split?
