There's been so much going on and so many links that I've lost track of where I found this, but I believe Marshall is on record as saying WSU would start a home/home series with CU and play in Omaha next year to start the series.
It seems it would be good for both schools. What I recall from other posts about CU's OOC schedule is that CU was looking for one home game and that was about it for next year. If that's right, 3G seems to have volunteered to provide that.
