I can't think of any way to quantify this, but I don't know what kind of hit ND would take in alumni contributions if they were to join the Big Ten. It's also hard to say whether it would be mitigated over the long term. But make no mistake, there would be a financial pricetag in terms of alumni donations if ND joined a football conference, and it would probably be pretty substantial.
landing spot. will be interesting to see how he does.
