I'm conscious that I've complained about officiating more than many people here, so I'll put this here....
You can't expect to get fair officiating on the road, especially in conference play. Fair or not, that's the reality.
I sorted BartTorvik by Defensive FT Rate, which is a good proxy for defensive foul rate. Michigan under Beilein was one of the least foul-prone teams in the conference and the country. Not so, now, and here is this year's Defensive FT rates by BartTorvik (National Rank):
1. Nebraska (2)
2. Illinois (7)
3. Maryland (17)
4. Rutgers (24)
5. Wisconsin (54)
6. Michigan (69)
7. Iowa (76)
8. Minnesota (87)
9. Northwestern (92)
10. Michigan State (107)
11. Purdue (109)
12. Ohio State (131)
13. Indiana (175)
14. Penn State (215)
These stats don't show it, but while I think BigTen officiating could be better and Big Ten teams do seem to get a better whistle in non-con play (even in major non-con games as opposed to just guarantee games), BigTen games tend to favor the home team and also seem to be somewhat inconsistent. It is what it is, though.
That said, foul aversion is not always a good thing (though it also does indicate that your team is in the lead at the end of most games, since otherwise there's no reason to foul, of course). There are smart fouls, of course, on players who shoot <60% that are worth fouling in late-game situations even if you're winning, so long as your defense has gotten the shot clock down to under 10 seconds for that possession.
