Return 6 starters on defense (Heagle- SS, Dudzik- FS, Smith- CB, Littlejohn MLB/OLB, Beck OLB, Emmanuel DE). Hardie- DE, Thorton- OLB, Champion- CB, are part time starters who have started in the past who return.
Offensively: Vraa- WR, Vaadland- TE, Haeg- RT (now LT) started last year. Crockett- RB (split carries with Ojuri), Woods- WR, Gebart- WR, Hinz- C, Schueller- G, Bonnet- FB saw plenty of action last year. Punter and kicker return.
Bohl, Vigen (OC), Stanard (LB coach), Kenny Burns (WR Coach), AJ Cooper (DE Coach), Scott Fuchs (OL), Gordie Haug (Offensive Assistant), John Richardson (Defensive Assistant) all went to Wyoming.
I think the philosophy will roughly stay the same. Play book may open a bit with new Qb Carson Wentz' arm (more vertical throws) and he's a little more athletic than Brock Jensen. New OC came from NIU and was with NDSU in the past. Not sure how much play calling will change.
