I mean, Foster Farms takes the #7 or #8 Big 10 team. Right now the following all look like they're going bowling:

Already eligible:
PSU (6-0)
OSU (6-1)
Wisconsin (6-0)

Will certainly get there:
Michigan (5-1)
MSU (5-1)

Will probably get there:
Iowa (4-2)

That's 6 right there. Then they just need two more out of the following:
Maryland (3-3)
Purdue (3-3)
Northwestern (3-3)
Minnesota (3-3)
Indiana (3-3)
Nebraska (3-4)
Illinois (2-4)
Rutgers (2-4)

Seems unlikely they won't get at least 8 eligible. Illinois and Rutgers have the worst records in the BIG, and neither is eliminated right now.
