I made a case on Friday for Pitt being in the top 15 team as an undefeated team from a power conference, but it's probably going to be tough given how the weekend played out.
Ranked teams this weekend were 15-2, with the two losses being No. 8 LSU and No. 24 Navy - and those two teams lost to other ranked teams (LSU lost to No. 14 Texas A&M; Navy lost to No. 12 Notre Dame). So there aren't any obvious options for teams that Pitt could leap-frog (or for SMU to leap-frog into the top 20, either).
Navy's loss did remove one more school from the list of undefeated teams, though. Now there are just 8 teams remaining who haven't lost a game:
Army (7-0)
BYU (8-0)
Indiana (8-0)
Iowa State (7-0)
Miami (8-0)
Oregon (8-0)
Penn State (7-0)
Pitt (7-0)
