Each week, an elite group of bookmakers and professional bettors provide Pregame.com with their private power rankings. These are numbers that literally influence the worldwide sports betting market -- and together are calculated into the Vegas rankings. Four categories tell you what the "experts in the desert" truthfully think about the teams:
TRUE POWER: How good Vegas thinks a team really is.
HOME-FIELD ADVANTAGE: The value of each team's home field.
BETTOR BIAS: How many points the public overvalues (positive numbers) or undervalues (negative numbers) a team without any justifiable reason.
POINT-SPREAD POWER: True power plus bettor bias.
To calculate the projected margin of victory for any matchup:
Take true power (home team), ADD home-field advantage and SUBTRACT true power (away team).
To calculate a the projected point spread of any matchup:
Replace the true power with point-spread power (which includes bettor bias, just like the actual Vegas line does).
