Developing a Rating System for SOM Hoops
by Dave Little
Passing ratings are assigned on the basis of points and possessions according to the following scale:
Precise points are determined by the number of passes thrown and the percentage chance of each outcome for a given pass. The number of passes thrown is a function of the action deck; assuming 100 possessions per game, the deck will assign 40% of these outcomes to passing cards in the following proportion: RG 12, LG/RF 8, LF/C 6.
The formula for the overall rating:
[(%Dazz * 2) + (%Open * 0.5) - (S% + T%)] * Position Rating
Example- Charles Barkley
Other examples: Laettner 0.15, Blaylock 6.9, Stockton 22.2
Fast-break passes are rated with similar assumptions. The differences here are that no "open" results occur, only turnovers, dazzlers, and standard FB shots. The standard FB shot, as the standard position shot in the half-court offense, is considered neutral. Turnovers on FB passing are charged against the passer's rating in this scale (although in the game, inexplicably, they are charged to the recipient of the pass).
Assuming 30 fast-break opportunities per game, fast-break passes will occur as follows:
RG 8.75, LG/RF 2.08, LF/C 0
The formula is the same:
[(Dazz% * 2) - (S% + T%)] * Position Rating
Sample - Mookie Blaylock
(On average, Mookie's dazzlers and turnovers cancel out)
Other examples: Stockton 4.38, Barkley, Laettner N/A at LF
