Not trying to be a smartass like some on here, and trying to fully understand what you are saying, didn't the line fade you are suggesting tell us to take AZ then? Last night it moved from opening at AZ -1.5 up to 2 then back to 1.5 right before kick?
I don't allow "where the money is" to effect what/how I bet. From previous experience, I learned that it just clouds my judgement.
Covers.com at 8 also, it stays at that take Houston, goes back to 7.5 good luck guessing. Goes to -7 take den though.
