I think Michigan State has opened its home season on the Friday night of Labor Day weekend for as long as we have done so on the Thursday night of that weekend, and perhaps for a season or two longer. That Friday tends to have a disproportionate number of college games compared to other weekends.
Having a Friday game that weekend is not a big problem in my opinion and it might help the Badgers get a better crowd for one of the conference's traditionally poorest drawing visiting teams when the Saturday afternoon of that weekend often gets used for other purposes as summer comes to a close.
The Big Ten is also doing what other conferences have done; scheduling at least one conference game every weekend to ensure the league always has a quality game for TV when most members are playing MAC, C-USA, and FCS type teams.
