What does all this say? First of all, a lot of it is on the defense. In the defeats, the Irish have allowed 44, 34, 34, 47 and 44 points. That's an average of 40 points per game in the five losses, an incredible hurdle for the offense to overcome. Secondly, everyone points to the pass defense and rightfully so. The deficiencies there have allowed these five teams to average 174 yards a contest running the ball. Another point: Notre Dame has a total of seven sacks in the five losses. A fierce pass rush has been missing in crunch time.
Also, in the last three losses, Ohio State, Michigan and USC have converted 17-of-36 on third down. That's good for a percentage of 47 percent, which is 13 points higher than the Notre Dame defense has currently in the category for the season. Turnovers are Weis's highest stat priority but the Irish actually have the margin advantage in three of the defeats.
On the offensive side of the ball, Notre Dame has scored 41, 31, 20, 21 and 24 points in the five losses for an average of 27 per contest. That's a difference of 13 points a loss. In the Michigan State contest, they started slow. Against USC in 2005, they executed the game plan perfectly. In the Fiesta Bowl, the offense had trouble doing anything against a speedy and tough Buckeye defense. This year, Michigan dominated the Irish up front and made Brady Quinn play possibly one of his worst games ever. On Saturday night, the Trojans' speed and overall talent level never allowed Notre Dame to find its rhythm.
What has also hurt this season is the ability to convert on third down. In the two defeats in 2006, the Irish are a combined 9-for-32 on the money down for a conversion rate of 28 percent. This is 10 percentage points below this year's mark of 38 percent and 21 points below the 48.9 rate in 2005.
