They've beaten Valparaiso(1-4), Savannah St (0-5), Portland St (0-5), and Idaho St (2-3).
I'm not saying they're not better than us right now, but they've proven nothing so far.
Also worth noting EWU played 2 FBS games in 2012 and 2013.
Regardless, NDSU has their scheduling philosophy, they can afford it, and it works for them.
Having played in the 4th game this season and needing a 6th year, he would need a waiver. Doubtful he'd get it, although he was injured his first redshirt year as well.
