Week 13 NFL Power Rankings: CBS Sports Leaves St. Louis Rams At No. 31

Pete Prisco of CBS Sports has released his Week 13 NFL Power Rankings, and the St. Louis Rams have remained the NFC's worst team, at No. 31. The move leaves them three spots below the No. 28 Arizona Cardinals. It isn't hard to see why the Rams couldn't make a move upwards, considering they allowed Patrick Peterson to gash them once again with a punt-return for a touchdown, and Sam Bradford has yet to truly make that return to rookie season form. It has all been pretty terrible in the recent weeks. 

Prisco isn't making any excuses with injuries at this point:

It's amazing how injuries can turn a team into a disaster in a hurry. This is far worse of a step-back season than anyone expected.

Here are the best and worst in the league according to Prisco:

Top Five

1. Green Bay Packers
2. Baltimore Ravens
3. San Francisco 49ers 
4. Houston Texans
5. Pittsburgh Steelers 

Bottom Five

28. Arizona Cardinals
29. Minnesota Vikings
30. Jacksonville Jaguars
31. St. Louis Rams
32. Indianapolis Colts
