What to watch from Notre Dame in Saturday's home game against Navy:

1. Michael Floyd: Apart from a victory, the No. 1 topic for the Irish this week is the return of receiver Michael Floyd, who broke his collarbone in Week 3 against Michigan State. Floyd likely will be eased into things this week, but he'll be needed next week against Pittsburgh. How does he respond to his first hit, and how quickly can he shake any potential rust off?

2. Stopping the triple-option: That's the challenge for any team playing Navy and its unorthodox offense. The attack becomes more dangerous with quarterback Ricky Dobbs back from injury, as he can run it or throw it. The Irish have injected more speed into their defense, but they're also using some inexperienced players like linebacker Manti Te'o and sophomore Darius Fleming. Will they be able to avoid mistakes against a team that lives to make you pay for missing your assignment?

3. The Notre Dame running game: Navy's defense has been strong this season, but if Notre Dame can't line up and win the battle in the trenches, then something's wrong. Armando Allen didn't play last week and has a bad ankle. Robert Hughes has been chugging along without him. This would be a good week to pound it some on the ground and keep that Navy offense off the field.
