I think going to 18 for the B1G with Oregon and Washington makes sense. Both are equivalent brands to Iowa, Michigan State, and Wisconsin and would be at least breakeven if not a net positive. Bringing them in at a 50% discount could satisfy the November NBC games and make up the gap in lost per school revenue caused by Warren. After those two, however, hard stop for the B1G.
