Each week, an elite group of bookmakers and professional bettors provides Pregame.com with its private power rankings. These numbers literally influence the worldwide sports betting market -- and together form the Vegas Rankings. Four categories convey 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.
POINT-SPREAD POWER: The combination of True Power and Bettor Bias.
To calculate the projected winner of any matchup:
Take True Power (home team), ADD Home-Field Advantage and SUBTRACT True Power (away team).
To calculate 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).
Biggest Improvement -- TRUE POWER
Biggest Drop -- TRUE POWER
