I'm concerned that, medically, everyone is not deemed fit to wade through a set of Power Rankings that haven't really changed after this deadly dull 16th week of the season. Be careful as you read this stuff. Find a sturdy chair. Do not read them if you are taking any kind of heart medication or if you are prone to dizziness. If, while reading them, you maintain an erect posture for more than four hours, seek medical assistance immediately.
