I pulled this from B-R.com:
1. Calculate points produced for each player. In 2008-09, James had an estimated 2345.9 points produced.
2. Calculate offensive possessions for each player. James had an estimated 1928.1 offensive possessions in 2008-09.
3. Calculate marginal offense for each player. Marginal offense is equal to (points produced) - 0.92 * (league points per possession) * (offensive possessions). For James this is 2345.9 - 0.92 * 1.083 * 1928.1 = 424.8. Note that this formula may produce a negative result for some players.
4. Calculate marginal points per win. Marginal points per win reduces to 0.32 * (league points per game) * ((team pace) / (league pace)). For the 2008-09 Cavaliers this is 0.32 * 100.0 * (88.7 / 91.7) = 30.95.
5. Credit Offensive Win Shares to the players. Offensive Win Shares are credited using the following formula: (marginal offense) / (marginal points per win). James gets credit for 424.8 / 30.95 = 13.73 Offensive Win Shares.
Discussion there is about Josh Smith, and why his OWS skyrocketed from 1.3 to 4.2 last year... anyone know where I can find the points produced, offensive possessions, points per possession, etc? Or are they only in Oliver's book?
Thanks.
