A lot of my own predictions are based on Wins Produced. Think of it as chemistry's STP. All conditions being perfect, all coaches being rational with playtime, their numbers are usually very correct. The predicted 63.7 wins is if Mchale plays his best guy the most. Using my one year sample of Mchale--his predicted win rate is -5. Out of the maximum amount of wins, he will lose 5 wins. Probably by playing Casspi 30% more often. 59 wins aint bad.
