Hmm. Not sure how I missed this the first time around. A stat I'm not too familiar with, called PIE:
"So I threw in a new stat that I haven't mentioned before - the PIE stat (or Player Impact Estimate). This is a stat produced by the NBA. Here is what we are told about it:
"It is a simple metric that gives an excellent indication of performance at both the team and player level. It’s a major improvement to our EFF Rating. Notably 2 things changed: (1) We included Personal Fouls, (2) We added a denominator. We feel the key here is the denominator because it acts as an 'automatic equalizer'. Using the denominator, we find there is no need to consider the 'PACE' of the statistics that are being analyzed. In its simplest terms, PIE shows what % of game events did that player or team achieve. The stats being analyzed are your traditional basketball statistics (PTS, REB, AST, TOV, etc..) A team that achieves more than 50% is likely to be a winning team. A player that achieves more than 10% is likely to be better than the average player. A high PIE % is highly correlated to winning. In fact, a team’s PIE rating and a team’s winning percentage correlate at an R square of .908 which indicates a 'strong' correlation. We’ve introduced this statistic because we feel it incorporates a bit of defense into the equation. When a team misses a shot, all 5 players on the other team’s PIE rating goes up."
Here's how to calculate PIE:
(PTS + FGM + FTM - FGA - FTA + DREB + (.5 * OREB) + AST + STL + (.5 * BLK) - PF - TO) / (GmPTS + GmFGM + GmFTM - GmFGA - GmFTA + GmDREB + (.5 * GmOREB) + GmAST + GmSTL + (.5 * GmBLK) - GmPF - GmTO)
Note that a rating of 10% is a player that is "likely better than the average player". Trey had a 6.75% rating in summer league play in his second year versus Cotton's first year rating of 10.33%. Cotton's second year rating jumped to 14.25% (my understanding is that "elite" players fall in the 15-20% range).
What were Cotton's and Trey's PIE rating for the 2014-15 NBA season? Trey came in with a rating of 8.5% and Cotton with a rating of 10.5%.
Getting back to the point. Cotton's first summer league numbers were similar to, if not better than Trey's second summer league stats; and Cotton's second summer league is head and shoulders better than Trey's. When you throw in the NBA season data, it's clear Cotton's the better PG right now."
