This is happening to all teams in the Summit... pretty much every season too. It's a way of life in mid and low major basketball now - you get gutted by the portal and you replenish via the portal. Even high majors have it happen to them - Baylor won't have a single player from last year's roster on next year's team.
NDSU's men will probably end up in the same place they always have in regards to their peers in the Summit - probably not at the top but nowhere near the bottom. Believe it or not Richman is actually pretty good at recruiting talent IMO. Developing that talent has been very spotty but maybe in the era of transfer portal musical chairs year-after-year development won't be that big of a deal anymore???
