posted this post on np.com and din't really get much responce, just thought i'd share it from an old hockey guy;
*warning. very long, rambling post about things some might not find interesting*
HOCKEY 404, TEAM BUILDING/POINT PREDICTION
have been pm'ed by a person asking how i come up with the prediction that we're 'only about an 85 point team' and have in the past fairly accurately predicted just about the point total we wound up at. so i thought i'd throw out so old hockey stuff from the past that some gm's did to 'predict' about where their team was going to be and what moves they might need to make. back in the early 80's i followed the oilers. the oilers had an old GM whose name escapes me now, that was generally considered to be a wizard building a team. he gave a series of interviews back then explaining what he did pre-season to best guess what lineup combination would equal about what final point finish for a team. something i mentally still use to SWAG (scientific wildazz guess) to guess what point total a lineup made of specific players should/most likely will ultimately probably produce.
the system he used basically went like this.
...he first divided players into 4 position categories. 1)scoring line type forwards, 2)grinding/checking line type forwards, 3)defensemen, 4)goalies.
...next he ranked each player in each postion category into whether he thought he was a 1)star, 2)an elite player, 3)an above average guy, 4)an average player, 5) a below average player, 6)a weak player
... for each of those 4 categories of player positions, each 'type of player' he had a number that he thought translated into a specific number of probable team wins, simply based on role and talent level.
...he then added up the expected daily 19 man 'win' total expected and from that could pretty accurately predict the number of wins any specific lineup should/would probably produce.
..for scoring line forwards he thought star players would equal about 8+ more wins over the course of a full season, that elite players would probably equal about 6 wins, above average guys 4 wins, average guys 2 wins, below average 0 more wins, and weak players would take away about 2 expected wins.
...for grinder forwards, he thought star level type grinders would translate into about 4 wins, elite 3, above average 2, average 1, below average 0, and weak grinders cost you 1 game each
..for defensemen, he thought stars would equal about 8+ extra wins, elite ones 6, above average 4, average 2, and below average 0, and weak ones -2
..for goalies, he thought stars would translate into 10+ extra wins, elite ones 8, above average 6, average 4, below average 0, and weak ones -4
confusing sounding stuff of course, but really simple if you can honestly judge talent and potential analytically instead of emotionally or thru hope.
for example let's look at our pre-season lineup we expected, what 'expectations' were and plug in his expected win numbers...
scoring line guys.. arnott 4(above average), erat 4(above average), legwand 4(above average), dumont 4(above average)jones 0(below average), hornqvist 0(below average).. so a net total of 16 wins.
grinder line type guys.. fiddler 1(average), bonk 1(average), nichol 1(average), tootoo 1(average), belak 0(below average)smithson 0(below average).. so about a total of 4 wins.
defensemen... weber 4(above average), suter 4(above average), hamhuis 4(above average), zanon 2(average), devries 0(below average), koistinen 0(below average).. so maybe 14 wins from the blueline.
goalies.. ellis 6(above average), rinne 4(average).. so 10 odd wins (note they have basically flipflopped)
so with everyone completely healthy and playing at just about expectation level you come up with about 44 expected wins (88 points). of course, you always assume everyone will not be completely healthy so even if everyone plays completely to potential, you have to subtract some number of points from the projected total to come up with the adjusted projected total based on players fitting their roles. he said he typically subtracted 3-5 points to account for probable missed time due to injuries.. which is basically where i came up with 85 points this year. and 91 last year (91 actual), and 110 the year before (110 actual) and 100 the year before that (106 actual), and 90 the year before that (91 actual).
as a further example, look at the 05-06 lineup we had and why the forecast was so much higher...
kariya 6(elite), sullivan 6(elite), hartnell 4(above average), legwand 4(above average), walker 4(above average), erat 4(above average).
perreault 1(average), johnson 1(average), smithson 1(average), hall 1(average), tootoo 1(average), hordichuk 1(average)
timonen 4(above average), zidlicky 2(average), markov 2(average), eaton 2(average), suter 0( below average), york 0(below average)
so going into that season using his methodology there was an expectation that lineup could win as many as 52 games. backing out probable injuries one could realistically guess that this team would put up about 100-102 points. (106 actual with the late adds of witt, weber, and especially sillinger)
it always surprises me how accurately this methodology can predict probable point totals. of course there are always extenuating circumstances. some people will outperform, some will under perform, injuries and adds will happen.. but it's still about as accurate as one can guess.
one thing a person can use this methodlogy to look at, is how trades or adds might affect final point totals to a specific team or possible trade or pickup.. for example, adding a superstar like ovechkin would in theory add about about 8 wins as a star to our current team if we picked him up in free agency.. it's always a domino type effect when you add player, in that that player replaces someone, so you have to back out whatever they would have brought you, and you also have to figure how one player might bump another and improve say your grinding line, etc.. so say an elite player replaces an above average player you get a net add of about 4 points (6 wins - 4 wins). but if that bumped guy, can play on a grind type line, maybe he becomes an above average grid type player replacing an average one so maybe you pick up an additional win because of that as well. but, if it takes losing two above average players, to afford a superstar, well the net, net is about the same. any more than that, and you even tend lose out in the long run if it makes you have to drop off anymore than that to sign a 'star'. (as pittsburg and atlanta are prime examples)
but i've always found it to be a pretty useful planning tool to try to maybe help quantify the unquantifiable.
apologize for the rambling nature and length as i've tried to type around phone calls and work.
