I am new to this, so maybe this is a dumb question, but I noticed that in some sports, on a daily basis, Heritage and 5Dimes have the exact same lines and they are posted at the exact same time for every single match in that sport. Now that can't be a coincidence. Either the two books have the same guy who decides the line, or they copy lines from each other (but the fact that the lines are posted at exactly the same time leads me to believe that this is not the case) or they get their lines from the same source. Does anyone have insight into this?
