Riley being the OC doesn't remove a position. We'll still get an OC.Bray/Cav/Read/Banker is 4, so that's 5 spots open.DB could be Warren (I hope so). DL might be Kaz, but maybe not. DL & DB could both be occupied by promising coaches on the Oregon State staff, if not by current Huskers.The remaining 3 we have RB, WR, and OC. TEs would also have to fit somewhere in there. Likely looking for new guys at all of these positions. Fortunately as an offensive coach, Riley should know a number of people in different circles he could reach out to. I wouldn't mind Brown being retained, but with Read on board it might be too much to go for another assistant without recruiting value.Personally, I like the idea of Langsdorf for OC. Familiar with Riley, worked with him, and working with Eli Manning this year. Well respected guy, lots of experience.
