Bo Pelini has said that he still has one more hire to get, he hasn't said who that is or what position. I think we can all assume its the TE coach. But it may very well be Special Teams and Defensive Line coach with the news about Papuchis
I don't think it's going to be a full-time assistant, but a Graduate Assistant. Joe Ganz was floating around on here a few days ago, so maybe he'll be the Offensive GA, with Ross Watson continuing as the Defensive GA. So the staff shapes up like this:
HC: Bo Pelini
OC/QB: Tim Beck
DC/DT: Carl Pelini
RB: Ron Brown
WR: Rich Fisher
TE: Brown/Cotton/Garrison
AHC/OT: Barney Cotton
OG/OC: Jon Garrison
DE/RC: John Papuchis
LB/ST: Ross Els
DB: Corey Raymond
GA: Joe Ganz
GA: Ross Watson
Not a flashy staff, but I trust Bo, look at Pap and Ek, I think Bo knows coaching talent when he sees it, so I'll trust his judgment on this one.
