Doesn't each team play 5 teams twice?
Yes. And the remaining two for each team hasn't been revealed yet. But they will be two of the five teams that were home/away two years ago (2014/15) Let's break it down with Iowa:
Teams we played twice in 2015/16:
Indiana, Michigan, Michigan State, Penn State, Purdue. We can't play back to back home/aways so these are for sure one game only.
Teams we've only played once in the last two years. (These we will have to play twice in 2016/17):
Rutgers, Illinois, Maryland.
Teams we played twice in 2014/15:
Ohio State, Wisconsin, Northwestern, Minnesota, Nebraska (Two will be picked for H/A this season, the other three must then be H/A in 2017/18.
Just for fun, here's the total Big Ten win/loss of our five H/A's last year:
15-3
13-5
12-6
10-8
7-11
57-33. Dang tough schedule. No way we'll face that and a big reason we could take this young team and make the NCAAs!
