Techincally, Greisel and Eady should be seniors this year. However, because of COVID, they are Juniors and can still use their COVID year if they want (however, it doesn't sound like they will use it).
It is also why Nelson isn't a Sophomore, he got to repeat this freshman year.
I think NDSU just left the classes alone for those who were effected with the COVID year and didn't move everyone up like what UND did and denoted Panoam as a 5th year player.
No correct way to do it, but it does make things annoying with the lack of uniformity on a team by team basis. Only a couple more years to cycle out the COVID year players.......
