For the second year in a row, Nebraska coach Bo Pelini is going into the final week of the regular season facing questions about his job security.

Nebraska followed a lopsided loss at Wisconsin two weeks ago with a home loss to Minnesota on Saturday. The Cornhuskers end the regular season at Iowa on Friday.

Pelini said Monday he's "turning over every stone" to win championships and that he won't be satisfied until he does. Pelini said he makes changes in the way the program operates every season in his attempt to "get over the proverbial hump."

Asked if he would fire one or more of his assistants if it meant saving his job, Pelini said he would not.
