Don't you think the infrastructure/logistics are different for staffing a 10,000 - 15,000 seat arena vs a 50,000 -110,000 capacity stadium?
They pulled it off in South Bend. Having been there 3 times, I'm rather impressed and I am sure it took over a year of planning to execute it. It's a rather remote place to get to with very little hotel capacity in the near vicinity.
Usually there are hundreds of campers on the outskirts of campus. Probably not an option last Friday. I'm sure there were lots of late night drives back to Chicago.
They previously hosted an NHL Winter Classic though, so I am sure the the ND Administration had that playbook to lean on.
