After opening up with a loss to Alabama, and then losing to a tough Notre Dame squad a few weeks later, Brady Hoke and Michigan are sitting at 3-2 with the nation's 10th toughest schedule. Only one team on their remaining schedule, Illinois (who they'll face this weekend), has a losing record. The combined record of the opponents remaining on their schedule is 26-12.
Steve Sarkisian's Huskies have played and lost at LSU and at Oregon and recorded a huge home win against Stanford at the end of last month. The Huskies are sitting at 3-2 with the toughest schedule in the country, and their next three games are against USC, Arizona and Oregon State who are a combined 11-4 (with three of those losses belonging to Arizona).
Just outside of the top ten in strength of schedule are Will Muschamp and the Gators (11th), who are sitting at 5-0 after road wins at Texas A&M and Tennessee, and their most recent win against LSU in The Swamp. They'll travel to Nashville to face Vanderbilt on Saturday and then have back to back games against South Carolina (home) and Georgia (neutral site).
Oregon State (4-0) and Notre Dame (5-0) are the only other undefeated teams with a top 25 strength of schedule. The Beavers are ranked 15th and the Irish are ranked 21st.
