From an athletic standpoint this move makes little sense. From an academic standpoint it makes no sense at all.
Nebraska thinks it can raise its academic profile by being associated with the Big 10 where every school, including now Nebraska, is an AAU member.
Rather interesting quote from Nebraska’s chancellor. He says that they “are more aligned the culture and academic mission of the Big 10”. Guess he kind of has to say that now that they’re joining the league.
