At this point in the basketball season for example, when an above .500 team is playing a below .500, aren't you going to pay more for the team with the better record then you should? Isn't the line value on the weaker team?
Take the first game on the board today. You have Xavier with a 15-6 record vs St. Louis that's 8-13. Doesn't Xavier get bumped up a point more than it should based on each team's records or will the market always correct any bias?
