For arguments sake ....
I remember a pretty good D2 UND team moving up to D1 (far later than they should have). At that point they had a pretty good name at the D2 level, and they moved up to FCS, so with your logic we should have had no issues recruiting against the NDSU, SDSU, UNI, Montana type schools .... right? Simply being an FCS team should be enough to win FCS recruits, just as simple being FBS should be enough to win FBS recruits.
Now obviously there is some satire and extremism in my response, but I think you get my point. I'm not going to say NDSU couldn't find some success at the FBS level, because honestly, who the hell know. They could jump up and surprise some people and give themselves something to build on, or they could struggle for a few years and really just bury themselves into an FBS hole, which would leave their FCS success as nothing more than a memory of what was (still a pretty great memory).
Now this isn't directed at you, but there are so many uneducated and dumb Bison fans (just as UND has a ton of uneducated and dumb hockey fans), who believe the team, program and success comes from the name. We're Bison football so we are untouchable, just as many UND fans think UND hockey should be untouchable even though there are a ton of other factors that go into maintaining success; there are only more of those factors as you move up.
This could not have been more well represented than by Izzo's comments in the last week. To essential say, NDSU can play for FCS Championships, or FBS Championships is the most ridiculous thing I've ever heard. NDSU is good and we all know it, but they are a far cry from a dominant Power 5 team that will win week in and week out against that caliber of talent. Now, I don't blame Izzo. He is doing his job and adding fuel to the fire where, as I mentioned, there is already a large subset of very delusional fans. Most aren't that delusional, but we all know there are truly those people who believe NDSU would be Alabama. C'mon Man!
