I do not begrudge any other program for having success. Having success means you are doing something right.
yes, there are different levels of football - so the best comparison is within levels. Within their level, NDSU is one of the best programs in the country. They are competing against other programs that play by the same rules (scholarships, budgets, facilities, etc.)
Within their level, the Gophers are not one of the best programs in the country. They have not been one of the best programs in the country for over 50 years.
If the Gophers dropped down to FCS, could they win national championships? possibly. If NDSU moved up to the Gophers' level, would they have as much success as the Gophers? Possibly. We can argue that point until eternity.
but, it does not change the fact that - at their level - NDSU has been a much more successful program than the Gophers. Having Gopher fans sniping at NDSU does not change that. In fact, there are very few teams out there that the Gophers can feel superior to. Maybe Fleck will change that. Only time will tell.
