The top half of the AP Top 25 could look much different after Week 4.
Five programs in the first 13 positions are involved in ranked matchups Saturday, with No. 7 Notre Dame and No. 3 Georgia headlining the schedule.
No. 8 Auburn's standing is at risk in a SEC West clash with No. 17 Texas A&M, while the winner of No. 11 Michigan versus No. 13 Wisconsin will likely leap into the top 10 with a quality victory.
There is a chance for movement at the back end as well since Washington, California and Arizona State all face tough matchups.
