I don't what was hurt by bringing in Quincy. They had a big gap in QB room seniority between Zeb Noland and Cam Miller. Quincy won every game he started and was a beast running the ball as QB2 later in the season which contributed to a national title. I'd think knowing how it turned out the coaches would've still brought him in.
The transfer portal is going to be part of the game no matter what going forward, I hope the coaches use it and take advantage of what NDSU offers transferring student-athletes. Some transfer will work out and some won't but the same can be said for high school recruits.
