What we learned from Notre Dame in its 23-21 loss to Navy on Saturday:
1. Charlie Weis is firmly back on the hot seat: Even with two losses in the first eight games, Weis appeared relatively safe because of the obvious progress the team had made and the bright prospects for the rest of the season. All that changed with a loss to Navy at home. Weis may have to win out and finish 9-3 to save his job now. At the very least, his status now becomes a major talking point and a possible distraction for a team that's not going to the BCS.
"It comes with the territory," Weis said Saturday night. "You know, the sad part about it is that's this job every week. It's a week-to-week deal. "
2. The red zone is a dead zone for Irish: For a team with such a high-caliber offense and such strong weapons at receiver, tight end and running back, Notre Dame is curiously bad in the red zone. That cost the Irish the game against Navy, as they scored just twice on six trips to the red zone. The other four trips resulted in two missed field goals and two turnovers, all of which are unacceptable. Notre Dame ranks just 75th nationally in red zone offense.
3. Jon Tenuta is under fire, too: Navy is never an easy team to stop with its triple option, but the Midshipmen embarrassed Notre Dame's defense for 348 yards rushing while controlling the clock. After the game, Irish players said the defensive game plan wasn't any different than it was last, and at least one player said the team was "out-schemed." That falls on Tenuta, who runs the defense while Weis operates the offense.
