Kelly: Irish can't get out of character

SOUTH BEND, Ind. -- A Week 6 matchup with Air Force presents Notre Dame with unenviable task of containing the triple-option offense. But coach Brian Kelly is hoping the new look doesn't force a defense that has played so good so far to get out of character.

"I just think being more familiar with it as a staff and being more familiar with it as the game unfolds are all experiences you can take with you," Kelly said Tuesday at his weekly news conference. "Certainly we have to play the way we've played. We cannot become so out of character in stopping the option that we forget about the things that we teach every day, and that is playing physical, flying to the football, great tackling.

"I think you've gotta be careful because sometimes option, you get the sense of, 'Hey, it's option.' But we have to do what we do and that is we got to play physical at the line of scrimmage and we've gotta tackle well a understanding the option as being the most important principle."
