Granted to hold there, we also need Iowa State to upset TCU this weekend, but now up to 7 ranked matchups on November 4.
To put that full Saturday in perspective, the matchups involving ranked teams (ignoring the USF-UConn and UCF-SMU Group of 5 games)
#23 LSU at #1 Alabama
#2 Penn State at #16 Michigan State
South Carolina at #3 Georgia
Texas at #4 TCU
#5 Wisconsin at Indiana
#6 Ohio State at Iowa
#7 Clemson at #14 NC State
#13 Virginia Tech at #8 Miami
Wake Forest at #9 Notre Dame
#10 Oklahoma at #11 Oklahoma State
Oregon at #12 Washington
#20 Stanford at #15 Washington State
#19 Auburn at Texas A&M
Arizona at #21 USC
#25 Iowa State at #22 West Virginia
So you have 15 games involving ranked Power 5 teams. 7 are where they play each other.
The other 8 opponents, based on Massey composite ranking:
#27 Texas A&M
#29 Iowa
#33 South Carolina
#39 Wake Forest
#41 Arizona
#48 Texas
#55 Oregon
#57 Indiana
So as of now the EASIEST opponents that any ranked team is facing that week are Texas, Oregon and @Indiana.
Mayhem!
