All correct @Taro T. Had to go back and look. The Ravens were in the top spot heading into this (past) week's games. When I saw PIT in 1st and BAL ITH it was after BAL had already lost but PIT had not yet been demolished by the Bills. So both losing resulted in no change in the standings. I can get this out of my turkey-filled brain now. 😀
... As I now see @Doohickie also explained.
