2015-2016 D-I Polls and Rankings

Re: 2015-2016 D-I Polls and Rankings

Clarkson probably too high. I think they would be underdogs against 7, 8, and 9.
 
Re: 2015-2016 D-I Polls and Rankings

Colgate at 10? Minnesota-Duluth, Princeton, Dartmouth, etc are better. I'm happy for the Colgate team as they are clearly better than last year. But this is not a top 10 team.

Then....

Minnesota starts out on top in the USCHO preliminary poll:

Preseason USCHO.com Division I Women's Poll
September 21, 2015
Team (First Place Votes) Record Points Last Poll
1 Minnesota (15) 34- 3-4 150 1
2 Boston College 34- 3-2 128 3
3 Wisconsin 29- 7-4 124 4
4 Harvard 27- 6-3 101 2
5 Clarkson 24-11-3 84 7
6 North Dakota 22-12-3 64 8
7 Quinnipiac 26- 9-3 56 6
8 Boston University 25- 9-3 49 5
9 Bemidji State 21-17-1 25 10
10 Cornell 19-11-3 18 9
Others receiving votes: Northeastern 11, Mercyhurst 6, Minnesota-Duluth 5, St. Lawrence 4.

And now....
February 22, 2016
1 Boston College (15) 34- 0-0 150 1
2 Minnesota 29- 3-1 134 3
3 Wisconsin 30- 3-1 121 2

9 Colgate 20- 7-7 25 10
10 North Dakota 16-11-5 16 9
Others receiving votes: Harvard 6.

No question that Harvard was the most over-rated team, having dropped from #4 in the preseason poll to the "Others receiving votes" category in the final regular season poll. :o
But for them the good news is: the season's not over yet! :)

I honestly don't understand how Harvard can still be receiving top ten votes. They lost 10 games including a key last game to Cornell, a team that is barely .500......the voters are lost in potential vs. performance...

Clarkson probably too high. I think they would be underdogs against 7, 8, and 9.

Considering they are 2-0 against #8 and 1-1 against #9 I highly doubt it. As for #7, western posters would make them an underdog and I would hope eastern posters make them a favorite. I know I would make them a favorite ;) .
 
Re: 2015-2016 D-I Polls and Rankings

I think it would be a coin flip. When I've watched Clarkson, it will dominate territorially, but not always have much in the way of goals to show for it. Clarkson would have the majority of the puck possession against Bemidji, but the Beavers are used to that. Where the Golden Knights would have to be careful is that they like to get their D involved around the offensive net, and BSU has some speed that can burn you going the other way. If Tiley is playing well, you'd probably be okay. One way or another, I'd expect a 2-1, 2-0, or 1-0 type game.

vicb... I wrote that about Clarkson in NOVEMBER. Their first half of the year was unimpressive. No one has made a bigger turnaround from H1 to H2 than Clarkson. I've got them at #5 and I'm confident they can beat anyone from #7 on in a 3 game series.

Who do you replace them with? Colgate is the only one in the discussion and Colgate is behind Harvard in KRACH and is 0-2 against Harvard.

Oh... and my #6 is Bemidji. I'd love to see Clarkson vs BSU.

Are you remembering to impose the non-quality result decrement on Harvard?

Anyway, the Colgate/Harvard question gets answered definitively on the ice this weekend. Until it is, let Colgate represent the placeholder.

I think it was answered pretty definitively by Colgate's non-quality 0-2 results against Harvard this season, one of which was literally this weekend.

If Colgate manages to suddenly sweep Harvard this weekend, then they deserve the spot, but as it is we have two head to head results to use here. Given that every ranking system we have has the two teams close, a worst, and Harvard ahead, at best, then I think H2H is pretty useful here, no?

0-2 AGAINST HARVARD THO

If Colgate wins two of three over Harvard this weekend, do you mean to tell me you're going to keep voting for Harvard because H2H 3>2? I'm saying for this one week, it is pointless to argue about it, because next weekend in Hamilton trumps everything that went before.
 
Re: 2015-2016 D-I Polls and Rankings

OK folks, we have the perfect opportunity to explain how the RPI is valid (for those that think it is) or invalid (for those who think it isn’t). WI & MN play the exact same conference schedule and finish with the same record. And they both lost & tied against UND, while splitting with each other. One would think based upon conference play that both should be ranked exactly the same, regardless of the ranking system used.


Now compare the non conference schedule:
Both teams beat all of their opponents. But it appears MN played the tougher schedule based on the opponents records. The SOS seems to agree with that. So how then, is WI ranked higher (even if only slightly so) than MN?

FYI, the opponents, note that they both played two games against an ECAC team, and two against a CHA team, conference record first, all games record second:
WI=
Dartmouth 6-13-3, 6-19-3
Lindenwood 5-11-1, 8-22-4
Providence 6-16-2, 10-22-2


MN=
Yale 9-11-2, 10-17-2
Penn State 6-8-6, 10-18-6
St. Cloud 9-15-4, 13-16-4

Yale appears to be a tougher opponent than Dartmouth, and Penn State appears to be better than Lindenwood. This is confirmed by SOS numbers as well.

And St. Cloud appears to be better than Providence, also confirmed by SOS.
So you would think MN would have the higher RPI & Pairwise.

How can any rating system that places WI above MN be valid given the above?

The argument here seems to be:
how should Princeton, Harvard, Colgate, or UND be rated with respect to one nother.
When you look at RPI/Pairwise, clearly, teams that play a tougher schedule are penalized in relation to teams that play a weaker schedule.
Of course this isn't news to anybody, least of all college coaches.
Which explains their reluctance to play anybody not a cupcake.
Why would they not want to fix a system that is obviously broken?
They complain nobody comes to watch women's hockey,
how about giving people a reson to?

Re: 2015-2016 D-I Polls and Rankings

I can try to explain just how RPI arrives at this result, though with the caveat that I haven't played around with the numbers at all. This explanation doesn't improve my opinion of the validity of RPI and PWR. Start with what I wrote in the Scores & Results thread over the weekend:

The PWR comparison between Minnesota and Wisconsin really tests the boundaries of the criteria. They split the head-to-head. They have identical winning percentages against every common opponent; the only difference there was Minnesota's Hall of Fame game against St. Cloud, but they both have the same 1.000 winning percentage against the Huskies. Wisconsin has a tiny edge in winning percentage (.8971 to .8939) based upon having played one extra nonconference game, but Minnesota has a larger margin in Opponents' Winning Percentage, as a nonconference slate of Penn State, Yale, and SCSU is substantially stronger than Dartmouth, Providence, and Lindenwood.

Consequently, Minnesota has a higher raw RPI than Wisconsin does (.6372 to .6313), but slips .0006 points behind (.6545 to .6539) once we're done tossing out all of the games that RPI isn't sophisticated enough to handle. Then they get .0005 of that gap back once you throw in the quality win bonus. So Wisconsin wins the comparison by the smallest visible margin possible.

God, RPI sucks. Fortunately, unless they both lose their semis in two weeks, we'll get some resolution to this issue.

What happens is that once the process discards those games that would lower each team's RPI, Minnesota's strength of schedule advantage is eliminated. There's no way to know exactly which games are being eliminated from the calculations without recalculating it for each possibility, stopping when all of the remaining wins raise the RPI, but my guess is that both teams' games against Minnesota State and maybe Ohio State are removed, along with all of Wisconsin's nonconference games and maybe Minnesota's games against Penn State.

When that's done, the two team's RPI strength of schedule components are almost identical. Wisconsin might even have an edge, depending upon exactly where the cutoff is. My assumptions above would leave either Penn State or Yale as the weakest nonconference team left in either's calculation, giving the Badgers a higher value. On top of that, because Wisconsin played one more nonconference game than Minnesota did, it has a higher winning percentage. Add it all together, and Wisconsin has an RPI for PWR purposes that is greater by such a small margin that it would be a rounding error with one fewer decimal places.
 
Re: 2015-2016 D-I Polls and Rankings

I said SOS when I meant RPI/Pairwise
comparing the non conference opponents, each of MN opponents are ranked higher than the comparable WI opponent using RPI/Pairwise
so The ranking system itself says that Yale is better than Dartmouth, Penn State is better than Lindenwood, and St. Cloud is better than Providence
common sense would say that if the ranking system ranks the opponents of team A higher than team B, if the ranking system is valid, then team A in that same ranking system would be ranked higher than team B

if it isn't there is something wrong with the ranking system.

normally if A> B
and C>D
and E>F
then it can be concluded A+C+E> B+D+F

but the RPI/Pairwise says, with some voodoo math apparently:
If A> B
and C> D
and E>F
then A+C+E is slightly less than B+C+F

the math doesn't add up

That's because you missed my point. I'll try again. If you look at the raw RPI, you'll see that everything you say is correct. The issue is that once you remove the games in which a win for a team lowers its RPI, none of your comparison of nonconference strength of schedule is in any way relevant to the question. As far as PWR is concerned, Wisconsin never played Lindenwood, Dartmouth, or Providence. What happens is that Minnesota's strength of schedule is lowered below that of Wisconsin, because the nonconference games that remain in its calculation have a weaker SoS component than its average games do, so while their RPI is overall helped by the additional win more than it's lowered by the SoS factor, it still leaves Minnesota with a lower SoS relative to Wisconsin than your analysis shows.
 
Re: 2015-2016 D-I Polls and Rankings

I suspect this is pretty much all there is to it.

Maybe. It all depends upon exactly which games are removed. It's possible that there are more wins removed for Wisconsin than there are for Minnesota, and so Minnesota ends up with a higher winning percentage but that this is not enough to compensate for Wisconsin's improved SoS.
