NBA Team Rankings - April 7, 2012
Here are the NBA Betting Market Team Rankings as of April 7, 2012. These rankings use the Vegas point spreads from recent games to derive an implied measure of team strength (Generic Points Favored, or GPF). By combining the point spread information with the betting over/unders, I can also decompose team strength into its offensive and defensive components (oGPF and dGPF). For more detail, see the Methodology page.
The Thunder have displaced the Heat from the top of the rankings this week, despite having lost three straight (including one to the Heat on Wednesday). The Thunder's last five games have been against the Pacers, Heat, Grizzlies, Bulls, and Lakers. That they were only able win two out of those five shouldn't reflect too poorly on them given the strength of the competition they were facing.
The Magic are once again in a tailspin, dropping from #6 to #18 in a single week. You can check their progress (or lack thereof) daily at The Ticker.

GLOSSARY
LstWk - The BTM ranking from last week.
GPF - Stands for "Generic Points Favored". It's what you would expect the team to be favored by against a league average opponent at a neutral site.
oGPF - Stands for "Offensive Generic Points Favored". The component of a team's total GPF attributable to its ability to score points (per game).
dGPF - Stands for "Defensive Generic Points Favored". The component of a team's total GPF attributable to its ability to prevent the other team from scoring points (per game).
GOU - Stands for "Generic Over/Under". It's what you would expect the betting over/under to be for the given team when playing a league average opponent.
W-L - The team's win/loss record (and win percentage rank)
GWP - Stands for "Generic Win Probability". I converted the GPF into a win probability using the following formula: 1/(1 + exp(-GPF/6.5)).
Additional Key Factors:
Additional Key Factors:
- League Average Points Scored (APS): 97.0 points
- Home Court Advantage (HCA): 3.25 points
- Back to Back Penalty (B2B): -1.25 points (see here)
How to Use This Table to Build Point Spreads and Over/Unders
- Point Spread (in favor of home team) = HCA + (B2Bhome - B2Baway) + (GPFhome - GPFaway)
- Over/Under = 2*APS + (oGPFhome + oGPFaway - dGPFhome - dGPFaway)
