A line comes out at -6. Lets say sharps get it down to -4 early on in the week. It stays consistent there until 15mins before gametime. From then on it moves up and down back and forth alot.
If the spread moves back up to 6 in the last 5mins, who is making it move?
If it moves down to 3 in the last 5 mins, who is making it move?
