What to watch: Notre Dame, Week 4

What to watch from Notre Dame in its home game Saturday against Stanford:

1. The fight in the Fighting Irish: Head coach Brian Kelly talked this week about how his team needs to develop "a nasty kind of tenaciousness." The Irish, in other words, need to get tougher to close out games. There are few better tests of that tenaciousness than Stanford, a physical team that takes on the bulldog mentality of its coach, Jim Harbaugh. Will Notre Dame be hard-nosed enough to fight back from its two-game losing streak?

2. Pressing Luck: Cardinal quarterback Andrew Luck is the No. 3-rated passer in the FBS after three weeks, and with Jake Locker's struggles, some say Luck could be the No. 1 NFL prospect in college football. He's also capable of tucking and running for a big gain. Stanford has a balanced rushing attack, but containing Luck will be key for the Irish. Getting safety Jamoris Slaughter back this week should help the secondary, though corners Gary Gray and Darrin Walls were nursing minor injuries mid-week.

3. Fixing Floyd: Michael Floyd caught two touchdown passes against Michigan State, but he also fumbled in the red zone for the second time this season. The star receiver still has a few flaws in his game that need to be fixed before he can have a true breakout. He and the Notre Dame offense will have to go against the top-ranked passing defense in the FBS, as Stanford has allowed just 90 passing yards per game thus far.
