Teams like the Patriots, Packers, and Bills are known to play well in cold weather, but what if the Miami Dolphins are traveling to Buffalo in December? The weather may shift the spread giving the Bills more points. Weather: Weather is an important factor in football where many games are still played outside.Amount of money bet: If a ton of money is already bet on one side, oddsmakers can move the line to even things out for that reason alone.If the Chiefs are 10 point favorites going into a week, and then we learn that Patrick Mahomes injured himself in practice and is now questionable, you’ll see that spread drop significantly.
How popular the team is: Nationally popular teams like Duke Basketball, The Dallas Cowboys, the LA Lakers, the New York Yankees, or Alabama Football receive a lot of betting interest, so oddsmakers may move the spread against them to ensure enough people are betting on both sides.
