It's a concern, I don't have any facts to back it up. So many muggings go uncalled in B1G play and officiating seems so inconsistent. The two teams I would guess most affected are MSU and OSU. Sparty plays physical D my rugby club would be proud of, and so does OSU. Plus I don't think refs from other conferences will allow Craft to saddle up opposing PGs like they do in the B1G.
