Here's a quick look at the overall efficiency statistics leading into the SMC game on Thursday. I've added some links to graphs that show the game by game trends per player and team.

Daye 17.139/gm (0.663/min)
Heytvelt 16.611/gm (0.593/min)
Bouldin 15.75/gm (0.522/min)
Gray 13.0278/gm (0.470/min)
Pargo 12.556/gm (0.412/min)
Downs 11.167/gm (0.441/min)
Sacre 4.8/gm (0.545/min)
Brown 4.778/gm (0.443/min)
Goodson 4.278/gm (0.303/min)
Foster 3/gm (0.438/min)
Sorenson 1.818/gm (0.5/min)
P-Maag 0.5/gm (0.286/min)

Zag Total: 100.194/gm
Opponent: 58.611/gm

Patty Mills (SMC): 16.868/gm (.502/min)
Diamon Simpson (SMC): 19.026/gm (.618/min)
John Bryant (SCU): 25.333/gm (.866/min)
Gyno Pomare (USD): 17.263/gm (.627/min)

just curious, but where are these numbers coming from? There is no way Daye leads our team in efficiency. I don't think this site uses the Four Factors for their determination. Based on azz's post I'm also thinking they overweight rebounding which is my Austin and Josh are tops for us, and why Big John, Simpson and Pomare are so high. How is Patty Mills as high based on his Poss% rate and shooting percentage? Just a thought.

The stat is calculated this way, and is a minor adjustment to a similar statistic used in FIBA.

Efficiency = (Pts+Rebs+Assts+Stls+Blks)-[{(FG Atts.-[1(2 Pt FG made)+1.5(3 Pt FG Made)]}+(FT Atts.-FT Made)+(Turnovers)]

This version gives more credit for 3 point makes. I've also thought about the inside people having higher efficiency scores, but I've also asked myself, is an outside player more likely to have 5 boards in a game or is an inside player more likely to have 5 assists in a game (in other words that can go either way). I think the biggest difference comes in the FG % (which I've tried to compensate slightly for by adjusting the credit for 3 pt makes).

I guess I'm surprised you're surprised that Daye could be our most efficient player.

In Europe, the stat is called the Index Rate, had to look it up, so I guess if that's a preferable name, I can be consistent with it.

I too am surprised, tightface, that you would question the greatness of Daye. Pomeroy also has Daye as our best player. Daye is listed as the only major contributor (http://kenpom.com/team.php?y=2009&team=Gonzaga). Austin rebounds, blocks a lot of shots, shoots for a high percentage, hits threes, and throws in a few assists and steals too. He is a complete player.

Pomeroys rankings are ordered by Possession rate not by "best" player. Poss% is a measure of how many of a teams possessions end with a shot (make or miss) or turnover by a specific player.

Just as a reference, some other players that are tops on their teams by Pomeroy, Josh Akognon the scoring guard from Cal Fullerton uses a ton of possessions but is woefully inefficient. A comparable all around comparison to Austin, Earl Clark at UL uses the bulk of the Cards possessions but isn't efficient offensively like Daye, making up for it on the glass and defensive ends. I'm interested to know where a guy like Stephen Curry rates in the Index formula, given his absurdly high Poss% and Assist rate (4th in the nation?!). I wonder if the three point weight in the formula will pull him down.

After reviewing the Index formula it makes total sense for Austin to be tops on our squad because of his incredible DRebounding and Block rates. As 03 noted, he is truly a complete player.

On a side note, it looks like the formula weighs turnovers higher which could be another reason why guards typically grade lower than posts.

As for Daye, I was thinking in terms of specific offensive efficiency. Given how well Gray has played this year I'm curious why it didn't show in that particular efficiency rating. He is far and away or most efficient Offensive player and uses a scarce amount of our possessions. Pomeroys lists Steven Gray as merely a "role player."
