I am not too concerned. In the past, fans not using tickets may have been more willing to let their tickets go unused completely... With a record/capacity crowd expected, it is now worthwhile to actually move unused tickets to people interested.... Because there are people interested! And it isnt just away fans... This is a good thing.
Marshall will bring a good crowd. That is fine. It adds to the atmosphere. Ohio had a great crowd in Huntington last year. I was with a large group of Ohio fans right in the middle of Marshall's horseshoe end zone seating because we bought tickets through their ticket office. It was great.
I knew this was the one Saturday home game I couldn't make when I bought season tickets. I was disappointed then and I am disappointed now. I moved those tickets to some other Ohio fans. I will be there in spirit and will also be checking my phone quite a bit at a wedding.
