Tough to tell when books are playing games or hinting at strong leans.
For example Houston Texans had less value last week to win the AFC before they beat Cincinnati than they do this week. It went from +700 to currently +900.
Now common sense says hammer NE but isn't that what the books want is to instill comfort to back the favorite.
I have been watching Superbowl match up futures and 1 in particular has dropped significantly in value.
