LINCOLN, Neb. (AP) Nebraska coach Scott Frost said Monday he doesn't know what prompted Indiana athletic director Fred Glass to say the Cornhuskers' staff doesn't respect the Hoosiers' football program.

Glass told the Indianapolis Star after the Hoosiers' 38-31 win in Lincoln on Saturday the victory was ''particularly gratifying, particularly knowing Nebraska's staff had no respect for our program.''

Glass declined to elaborate, other than to say, ''They know, and I know, and our team knew, and I'll just leave it at that.''

Asked if he or his staff said or did anything that would have led to Glass' comment, Frost said, ''We've been scratching our heads wondering what that's all about. We don't have any idea, to be honest with you. I would be curious to know.''

Indiana coach Tom Allen didn't address the matter at his Monday news conference.

Frost congratulated the Hoosiers in his third sentence at the postgame news conference. He said he told Allen he could see great improvement in the Hoosiers and that they earned the win.

''I couldn't have been nicer, more complimentary to coach before and after the game,'' Frost said. ''We had a ton of respect for their team and where they've gotten their team to.''

Frost added he told Allen that Indiana offensive coordinator, Kalen DeBoer, was doing an ''unbelievable job'' and that he was happy for the Hoosiers.

''If there's something we did, I certainly would like to know,'' Frost said. ''But that's a dead issue to me. We're going to treat every opponent we play with respect, and they're certainly having a good year so they deserve the success.''
