What a weird phenomenon. Is there another college football fan base that grew tired of winning? If that really is the case, the new decade should have peaked some renewed interest. While NDSU dominated FCS and the MVFC from 2010 to 2019, since 2020, NDSU has only won 2 of 6 national championships, and 2 outright and 1 shared MVFC conference title. SDSU, Montana St and maybe even Montana have caught NDSU in competitiveness and resources. USD and even UND have closed the gap. Bison wins weren't as inevitable as they were in the first half of the last decade as peer schools poured the same kind of resources into their FB programs.
I'm sure there will be a spike in interest in NDSU football but I would argue that for the Bison, the fanbase is not particularly large and not particularly rabid but that there is a small subset of rabid fans. Frankly, the best fans in FCS are at Montana St and particularly Montana. The Griz fans sellout a 25,000 seat stadium game after game, year after year, for pretty disappointing results. We'll see how rabid of fanbase it is two or three years from now when instead of pounding Northern Iowa, they're licking Wyoming and playing in the New Mexico Bowl against Georgia Southern. Or, if its competition they want, losing to UTEP or someone equally unmemorable.
