It's been a long time since Notre Dame has been in the national title picture, but the No. 5 Irish are back in the conversation at 7-0. They can prove they're truly worthy on Saturday night against No. 8 Oklahoma. Linebacker Manti Te'o (left) has been a dominant force on a Notre Dame defense allowing just 9.4 points a game, but can it handle a high-scoring Big 12 offense? Oklahoma quarterback Landry Jones and the Sooners are averaging 52 points in their last three games after struggling earlier this season. The Irish made a goal-line stand against Stanford in overtime two weeks ago to remain unbeaten, but can they keep the "The Belldozer" Blake Bell (right) out of the end zone?
