Kelsey 2nd Nationally In Goals Against

Guess who's number one? Why Ashley Thompson, UCLA, of course!

Ashley's allowed just 3 goals in 16 appearances. Kelsey has given up only 4 goals in 16 appearances also.

Ashley's GAA, (goals against average) is also #1 @ 0.196. Kelsey's GAA is 2nd @ 0.248.

One important note: Kelsey has played 70 more minutes than Ashley.

GK NCAA DIV 1 GAA

Can someone with a brain please explain how they figured GAA, being as each keeper has played different minutes.

Near as I can tell they normalize the data for 90 minute games. That makes a 110 minute overtime game worth 1.222 games.

Take the total number of minutes played and divide by 90 (minutes in a regular game). Then take the total number of goals against and divide it by the the number you just solved for.

Thompson: 1378 minutes/90 = 15.31
3GA/15.31 = 0.1959 GAA

Davis: 1449 minutes/90 = 16.1
4GA/16.1 = 0.2484 GAA

Here is the formula for your convenience:
# of goals against x 90 minutes per game divided by minutes played= GAA

Ashley Thompson
3 x 90 = 270 divide by 1379 =.196

Kelsey Davis
4 x 90 = 360 divde by 1449 = .248

Hope this helps.

BTW unless you keep doing well one bad game can send you sliding down the rankings FAST. Kelsey had a .2 going something last year and the UCLA game send her down to number 9 I think.

KFTC you beat me I guess i owe you a beverage.

But mine was understandable. I get a beverage too.

Geez I owe you several beverages. The Brazilain Soccer Name game kept me entertained all weekend not to mention the rest of your insights. And thanks to FANatic for asking the question. I hadn't had the calculator feature out in a while.

All right! Finally, some math on this site! That's more like it! And beverages, too.

99 bottles of beer......

Sorry Geez, probaby more like 85, some unknown person may or may not have taken some while you weren't looking....

Thanks everyone! I now get it!

This does gives me an extra dose of confidence going into the playoffs. We know we have a GK who is going to be very difficult for any team to score on. But also, we know by the number of saves and SOG, that we have have a very solid defense in front of her.

Michelle O. moving to holding mid to replace Keelin we know is a risk we must take. However, people have talked about Michelle's poise, calmness and leadership all season. Does anyone really think she is suddenly going to be a liability? My money says she will rise to the occasion and excel.

Similiarly, Kassi and Michelle O. have seemingly formed a brick wall at center back. But Korie is playing back there now with Kassi, and Korie apparently is continuing to improve. Kassi is rough, tough and has the attitude you want in a leader on the back line. She's afraid of no one, and Korie is also a big and tough defender. Kristen is the back up at center back, and hopefully any playing time she can pick up is certainly very valuable.

At outside back, it seems unanimous on this board that Jessica Tsao is all-conference worthy. Megan Sweeney is solid but doesn't seem to have the speed she had two years ago before she missed last year with a knee injury. She also left the last match against St. Mary's early in the game and never returned. I don't believe we have heard if she is hurt or not. Emma Nelson played in her spot for I think her longest stint of the season. I haven't seen Emma play or heard much talk about her. I do know coming to the Pilots, she was advertised as being a speed demon, which is a positive for that position.

For all of you out there, particularly those of you that have seen the team play a lot this season, I await your comments.

But mine was understandable. I get a beverage too.

Understandable, sure. But not completely accurate.

I've never seen the formula you gave before, Auto Pilot. It's an interesting method. I got mine from an old NCAA statistics manual when I was trying to figure out how they figured GAA about 10 years ago. I'll still take you up on that drink though.

I picked up that formula from a baskeball calc and adjusted the 60 minutes to ninety minutes. I like yours better. I think I got a little wordy about it. Same result though.

Fanatic, I agree with your assessment for the playoffs. Concerning Emma, I have seen her play when she's been in at the home games and she seems to have what it takes to be successful at her position. Her only downside is her lack of playing time which is understandable with the skilled players ahead of her on the depth chart. I remember during the season ticket holders pre-season scrimmage on one particular play she was defending Michelle E. and was with her stride for stride down the left side which would seem to confirm the speed you mentioned.

KFTC and Auto Pilot have it right. This is like a conversion problem in a freshman chemistry class.
We have goals allowed (GA) and total minutes played, so:

(GA/minutes)*(90 minutes/game)

The minutes cancel and you get GA/game, or GAA.

I think it should go to four decimal places since we have four significant digits in the minutes played figure (the leading zero in the GAA is not significant).

(I like early English literature as much as the next poster, but I figured math and science were fair game, too...)
