SMQ: Where did Week 7 rank among most upset filled weekends of all time?

What is the highest number of top-10 teams to fall on the same weekend?

There is only one weekend since 1950 where six top-10 teams tumbled on the same weekend. That level of chaos took place in 1956, when the upset bug struck a half-dozen top teams across the country on October 27.

TCU and Ole Miss, tied at No. 10 in the AP Top 25 entering that week, both lost in shutout fashion to No. 19 Miami and unranked Arkansas respectively. Unranked Illinois took down No. 1 Michigan State in Champaign. The Spartans’ rival in Ann Arbor similarly stumbled, as No. 5 Michigan fell to unranked Minnesota. No. 6 USC fell 27-19 on the road against unranked Stanford. The sixth loss wasn’t as surprising, as No. 7 Texas A&M took out No. 8 Baylor 19-13 in Waco. But it did render the most chaotic weekend in college football history.

Week 5 in 1963 comes in at a close second. Five top-10 teams lost on October 12, 1963, while another sustained a tie against an unranked opponent. No. 3 Alabama fell 10-6 to Florida. Notre Dame dropped No. 7 USC 17-14 in South Bend. SMU knocked off No. 4 Navy in Dallas. Army took out No. 9 Penn State in Happy Valley. And No. 2 Texas crushed No. 1 Oklahoma 28-7 in a lopsided edition of the Red River Shootout. Then there was No. 8 Ohio State, which drew 20-20 against Illinois in an era before overtime.

On no other occasion have six top-10 teams collapsed on the same weekend.
