Number Crunching

Let's look at some of the numbers here
These formulas are taken and modified from the Dean Oliver book "Basketball on Paper"
It helps to see things on a possession basis. Also these are only 3 games worth of comparisons, but it helps to see what is going on.

INDIVIDUAL OFFENSIVE RATING
scoring over possessions rated out over 100 possessions
Gina Jaroszewski, Moorhead 187.5
JaRae Ellefson, Buffalo 157.1
Danielle Cook, Moorhead 123.5
Macie Michelson, Marshall 115.4
Nikki Anderson, Moorhead 112.5
Jessica Onken, Marshall 111.1
Kate Thompson, Wayzata 111.1
Jenny Greig, Edina 108.3
Lauren Young, Edina 106.7
Kate Gilligan, Edina 100
Krissy O'Toole, Wayzata 100
Kate Coughenour, Wayzata 100

All this shows is what a player would have done for 100 possessions from that game. Moorhead has three players rated fairly high. Buffalo did not do a very good job defensively on these players. Also Jaroszewski probably needed to get involved in the offense more since she converted so often. She only had 8 possessions (but 15 points---very efficient). She is Moorhead's leading scorer on the year averaging 13.1 ppg with 8 double figure games, and 2 20+ games so far.
Ellefson from Buffalo came into the game in the second half and ripped it up. Was that a fluke? Coming into the game she was averaging 4 ppg. The smell of fluke is in the air. It will be important for her show the same consistency and fire in the coming games. One hit wonders fade like a streaking comet in the night sky.

INDIVIDUAL FLOOR %
Scoring possessions divided by total possessions
Gina Jaroszewski, Moorhead .875
JaRae Ellefson, Buffalo .857
Danielle Cook, Moorhead .647
Lauren Young, Edina .600
Jessica Onken, Marshall .556
Krissy O'Toole, Wayzata .538
Nikki Anderson, Moorhead .500
Jenny Grieg, Edina .500
Kate Gilligan, Edina .500
Macie Michelson, Marshall .467
Kate Thompson, Wayzata .400
Kate Coughenour, Wayzata .333
Does this mean if we took the top five players here and made a team they would clock everybody? Probably not, but what it might mean is these players take good shots, at good times, on balance, and don't throw the ball away. Also the bigger numbers go to post types (Onken, O'Toole, Cook, Anderson, Gilligan).
What about the other games I have charted? I haven't crunched their numbers, but I might do some individuals that had interesting games just to compare with what I have seen so far.

TEAM OFFENSIVE RATINGS
Breck 124.0
Minneapolis Roosevelt 107.5
Hill-Murray 107.4
Apple Valley 106.0
Hopkins 102.4 (3 games)
St. Paul Johnson 100
Since the New Year the teams I have seen have not been real effective on offense. Two teams have managed to crack the 100 barrier Breck with 124 against Marshall and Hopkins with 102.3 against Henry Sibley. This might be due to the fact that conference play is under way and teams know each other better.
If we are looking at just one game Hopkins with 125.5 (against Cretin-Derham Hall) is 1.5 ahead of Breck's best.
The average offensive rating for HS is 83.1

TEAM FLOOR %
Breck .580
Hopkins .522 (3 games)
Hill-Murray .500
Edina .492
Park-Cottage Grove .467
Cretin-Derham Hall .425 (2 games)
You have to understand that these numbers relate to only one game, it is not a season. It is like looking at a photograph and describing a movie. There will be more information coming in to give this life. I will say that the teams above .500 were effective on offense, knew the difference from a good and bad shot.

TEAM FLOOR % Defense
The Case of Marshall. Marshall played two metro teams on the past two weekends and they have different results for each game. Against Breck their D% was .580; against DeLaSalle .319 the total would be .429. What a difference a week makes.
