Oof - That's a tough week. The news about Scott is the biggest as he's the most talented corner (by far?) and the unit is still shallow. He would be a big loss for any games, but I still wouldn't expect them to lose to Arizona State, IU, or Northwestern. Two of those are away games, though (@ASU, @IU) and the Big Ten has a bad history of PAC games played on the west coast, so I may be underestimating.
Still, I think they'll come out unscathed. To me, the bigger concern is whether 2 months is enough recovery time for JS to return at or above his playing level from 2017.
