With how close they are to many very good FBS programs, you cannot fault them for picking up FBS guys that are stuck on the bench.
Look at Southern Illinois, they always bring in a ton of FBS guys and look where that has taken them.....
This. If NDSU were located where they are we would be doing the same thing. If your recruiting class has high FBS attrition it makes some sense getting some of those kind of players back along the way.
