Looks like Fedor, Scott (to JuCO per Twitter), Dadaboe and Nolden are missing from the 2019 Spring Roster. Coulld be they graduated, transferred or are medical redshirts, WR looks light in regards to speed unless Nunn becomes the "go to" deep threat.
Seems like a lateral move at best, unless the $$ is that much better (which is hard to believe). DeKalb is a very rural location, and not a place you would move to for location (unless you want to be closer to Wisconsin or Minnesota) or because of the campus setting. This seems like a big loss, as the OL has been very good. Best of luck to Daryl and his family.
