Ah yes, I forgot about Toivonen and Maag. I recall Toivonen getting some playing time and even a few catches in pre-season games. His body type got him the opportunity and he did quite well with his opportunity, but it still wasn't enough for a roster shot unfortunately due to a pretty stacked roster that year.
Still pretty wild that quite a few local NSIC D2 teams have been producing comparable numbers of NFL talent as UND. Mankato, Augustana, UMD, and even the late St. Cloud team had a few recently. Mankato likely the most impressive list since 2010 in Thielen, Chris Reed and Shane Zylstra who all had/have substantial playing time holding starting positions for multiple years. Hell even lowly late UMC had a kid who played there for 2 years before they folded and he transfered to NDSU and is still playing in the NFL (Mason Miller).
