NBA 2014: 3-week Power Ratings

If we look at the NBA’s regular season as if it were a 48-minute game, then we’ve reached the six-minute mark – the first media time-out, if you will.

It’s hardly news that the league’s power lies in the West, and the initial set of power ratings seems to affirm this notion – five of the Top Six and seven of the Top Ten.

These rankings reflect the first 21 days of the season (through Monday Nov. 17).

Power Ratings --The Measurement Instrument

Our team-ranking tool utilizes four elements. Two scales are based solely on team wins and losses; the others are measures of the efficiency of team performance in comparison with the competition. First, we’ll simply use win-loss record irrespective of conference.

The second criterion will be the difference between a team’s road wins and its home losses. Since this cute little metric is said to be a personal favorite of veteran NBA coach George Karl, let’s call this the Karl Kount (KK).

Criterion No. 3, Conversion Quotient (CQ), involves the rate at which a team converts its possessions into a successful field goals or free throw attempts. Like the KK, the computation is simple subtraction—a team’s rate of offensive efficiency minus that of the opponent.

Lastly, please allow Abacus to introduce the “SPOR-t” score. SPOR-t stands for “Shooting Plus Offensive Rebounds minus turnovers.” Add a team’s FG percentage and its offensive rebounding percentage (o. boards divided by missed FG’s). Then subtract the percentage of a team’s possessions lost to turnovers. For example, a team shoots field goals at a .488 clip, its offensive rebounds account for .199 of its missed field goals, and .143 of its possessions result in a turnover. So its SPOR-t is (488+199-143) or 544. Once again, our measurement will be the difference between the SPOR-t scores of a team and its opposition.

We’ll rank the teams from 1 to 30 in all criteria and simply add up the rankings. Low score wins, naturally.
