I agree. If I was a betting man, I think Chiefs/Texans is a 4pm game and Bills/Ravens is an 8pm game.
If the Commies win, it would put Lions/Commies on Saturday at 8pm (Chiefs/Texans 4pm Saturday, Eagles/Rams-Vikings 4pm Sunday, Ravens/Bills 8pm Sunday).
If the Bucs win, Lions/Rams is an 8pm Sunday game, bumping Ravens/Bills to 8pm Saturday and Chiefs/Texans to 4pm Sunday, Eagles/Bucs to 4pm Saturday... Lions/Vikings I'm not so sure. That might get 4pm Sunday, with Eagles/Bucs taking 8pm Sunday.
on edit, I'm not so sure about Lions/Commies either. It's probably an 8pm game, but they might like Eagles/Rams more.
