Title: Change in NCAA selection criteria

Wondering if this will typically hurt CU/ECAC Hockey in the long run or is it of no significance ?

It tugs both ways, given the limited OOC schedule that the ECAC, and the Ivies in particular play, but I think it helps the ECAC. Other conferences can play in-conference foes 4 times a season. Win that game and Cornell gets at least a push; the CCHA bubble teams have to have a 4 game sweep to win that comparison.

If I'm reading it right, I think this puts a premium on the number of different schools you play.  I you play 4 games against 4 different schools and win all four, you get four points (4 x 1.000).  But if you play one school 4 times and win all 4 you get 1 point.

True, assuming you win them all, different if you lose them.:-D

Remember that this is a pairwise comparison.  It is just a different weighting of the games against mutual opponents when you are being compared to School X.  If you play 4 different schools 1 time each, winning them all, you only get credit if School X has played exactly those 4 opponents, too, getting the chance to tally the same 4 points.  If you play 1 school 4 times, you can get anywhere from 0 to 1 points (in increments of 1/4) in the comparison, but it is only School X's record in N games against that 1 school that earns it points between 0 and 1 (in increments of 1/N).

Do you by any chance write bills for Congress?

The way I understand it (and I very easily could be wrong), if team X and team Y have 4 common opponents (A, B, C, and D) and their records against them are:



Opponent    X     Y
A           1-0   4-0
B           1-1   0-1
C           0-0-1 0-1
D           2-0   3-0



Under the old system, X was 4-1-1 (.750) and Y was 7-2 (.778), so team Y won the comparison.  But what if team A and team D are the absolute worst teams in college hockey?  Team Y loaded up their common opponent record with 7 wins against those cupcakes.  Team X would have undoubtedly beaten them every game, too, but did not have the opportunity to play them so many times.  Under the new system, X and Y have equal records (1.000) vs A and D, so those are a wash.  Team X has a better record against B (.500 vs .000) and C (.500 vs .000), so overall X has a better record against 2 opponents and Y has a better record against 0 opponents, so X wins the common opponents comparison point.

Are we saying the same thing?  Do I have it wrong?

"If I'm reading it right" should be everyone's preface to this discussion.

The brief story says it's meant to discount the effect of multiple victories over a crappy opponent by counting each series (games against an opponent) as a won-lost percentage. The example has one team (A) going 3-0 against the bad team and 0-2 against the good team. The second team (B) goes 1-0 against the bad team and 1-2 against the good team. The old way, A won the pairwise. Now B wins the pairwise. If you fill in Providence for the crappy opponednt team and Yale for the good team, it makes sense that the team that ekes out one win in three tries over Yale deserves a little more credit than than the team that went 0-2 against Yale.

It still will get us placed in the Gopher State bracket, against Minnesota, at the Minnesota rink, and all cowbells will be confiscated. Same as the old system.

It seems to me, at least from that article, that X's records are 1.000, .500, .500, and 1.000 against the four opponents, respectively, while Y's are 1.000, .000. .000, and 1.000, respectively. So X wins 3.000 to 2.000. This could turn out differently than your interpretation, but I leave it as an exercise for the reader.

It isn't the same thing and I think ursusminor is correct. Take for example:


Opponent    X     Y    %    
A           1-0   4-0  -
B           1-1   3-2  Y: .1
C           0-0-1 3-2  Y: .1
D           2-0   3-0  -
E           1-0   1-4  X: .8


Y wins more H2H matchups, 2-1 with 2 ties, but X wins the comparison (X: 1 + .5 + .5 + 1 + 1 = 4;Y: 1 + .6 + .6 + 1 + .2 = 3.4). It isn't just number of comparisons won, it is also how decisively the comparisons were won.

Under this lens, this encourages certain new, smaller conferences to play a more robust and varied OOC schedule, instead of being insular and provincial, right?  Doesn't this also create an incentive for the "big name" programs to schedule the smaller, "minor conference" teams?  It probably discourages scheduling a 2-game weekend OOC series as well.

It's this bit that I find intriguing (and agree with).  The ECAC has the potential to benefit from western teams having a new reason to come east (two teams in one weekend that is far less practical out west).  It's a lot harder to go the opposite direction.  Teams within an easy drive of NYC and Boston are ideally situated to take advantage as cost plays a big role.  Two western teams could pair up and play two eastern teams that are relatively easy to get to as happens somewhat sporadically now.

Another note is that this would seem to put an incentive on in-season tourney organizers to diversify the field as much as possible.  May also result in more such tournaments hosted by the big boys in lieu of weekend series.  

Can they finally ditch the Ivy Showcase?

You're right, I missed the fact that it was a comparison of common opponents.  I was applying it to the general TUC record.
