TSN Power Rankings

Just saw the Sporting News NFL Power Rankings:

1. Tampa Bay Buccaneers
2. San Francisco 49ers
3. Kansas City Chiefs
4. Cleveland Browns
5. Los Angeles Rams
6. Arizona Cardinals
7. Buffalo Bills
8. Baltimore Ravens
9. Seattle Seahawks
10. Pittsburgh Steelers

Now call me a cynic but.... Raiders beat #8 Ravens last week and #10 Steelers this week in Pit. and a still ranked below both in 15th....???
