Online betting odds makers used to be extremely sensitive to injuries in the NFL and how those injuries could affect the outcome of a game. But what was happening was that the action on a particular game was begin skewed based on the perceived value of a player to a team. For example, if the Ravens’ running back was injured for a game or two and the perception was that he was a key piece of the offense, then the action would be heavy against the Ravens and the line would change to reflect that.
It did not take long for the price per head bookie experts to catch on to the way that injuries affected action and the appropriate measures have been taken to adjust the odds based on reality rather than perception. For example, if Aaron Rodgers is injured and cannot play, then that definitely will affect the outcome of the game. Rodgers is extremely valuable to the Packers and there is a history of the Packers being unable to win without Aaron Rodgers. But if the quarterback for the Buffalo Bills, whoever that may be at the time, is injured then that will not swing the results of the game even though the perception that an injured quarterback is significant.
It is that balance that odds makers try to keep in order to avoid a betonline scam. If the Bills are -7 in their first game without their starting quarterback, then the fact that the quarterback is out of the game is not going to push those odds to -10. The odds will stay the same to avoid giving the Bills an unfair advantage in the odds. It is just one way that betting experts try to keep the playing field level by using realistic information to create odds rather than public perception.
