Another defensive starter out of the season — Kramer announces Manu will miss entire ’15 campaign

And we have another preview of an Idaho State opponent ...

BREAKING DOWN ISU'S SCHEDULE — Montana

ISU will release its starters for Black Hills State on Wednesday. Until then, here's my best guess for the starting defensive unit ...

3-4 BASE DEFENSE

E - Tyler Kuder

NG - JonRyheem Peoples

E - Chris Edwards/Drew Sharkey

Rush - Kurt Karstetter

Sam - CJ Langlow

Mac - Hayden Stout

Will- Jake Pettit*/Joe Martin

SS - Kamino Ward

FS - Cody Sorensen

RCB - Khary Livingston-Coleman

LCB - Erik Collins

*expect Pettit to start if he's heathy enough

NICKEL DEFENSE

E - Tyler Kuder

T - JonRyheem Peoples

T - Chris Edwards/Drew Sharkey

E - Kurt Karstetter

Mac - Hayden Stout

Will- CJ Langlow

SS - Kamino Ward

FS - Cody Sorensen

Nicklel - Erik Collins

CB - Khary Livingston-Coleman

CB - Tavonte Jackson

NOTE: Idaho State has several options in its nickel defense. Junior safety Jeremy Bittle, another player who was hurt and not practicing last week, has been used extensively in ISU's nickel package when he's healthy. Sophomore Nikko Hayes, a converted running back, is an interesting option at safety once he's more familiar with the position. And along the defensive line, expect the Bengals to deploy freshman DE Rasheed Williams and freshmen defensive linemen Treven Aloi and Robert Schwenke. And don't forget about Spencer Hoff, the JC transfer from San Bernardino Community College. He's missed most of fall camp, but is expected back at some point.

Notes from the #BigSkyFB coaches call today: Idaho State senior safety Taison Manu is out for the season according to HC Mike Kramer.
