With two weeks left in the regular seasons of the four major conferences and four weeks until the NCAA Tournament is seeded, here's another dry run through the NCAA Tournament selection procedure using the results to date from US College Hockey Online's Division I Composite Schedule. This week there 25 teams under consideration (i.e., with .500 or better records against tournament-eligible competition), which have the following pairwise comparisons with one another:

For the first time this season, we know two of the tournament participants without a doubt: Michigan State in the CCHA and North Dakota in the WCHA have wrapped up their conference regular season titles and the associated automatic bids. The two Eastern conferences are up for grabs, but for this excercise we assign those bids to the current leaders: Clarkson (one point ahead of St. Lawrence) in the ECAC and Maine (whose game in hand gives them a better winning percentage than New Hampshire, despite having one point less) in Hockey East. We gained a little more information on the relative strength of the MAAC to the other conferences this week when Division I independent Army tied Iona while losing to Hockey East's Mass-Amherst. That did little to change the picture:
vs Indies vs Army vs Niagara vs AFA vs Mankato
Avg RPI PF-PA Pct PF-PA Pct PF-PA Pct PF-PA Pct PF-PA Pct
HE .527 14- 2 .875 12-0 1.000 0- 2 .000 2-0 1.000 0-0 .---
WCHA .506 28- 8 .778 0-0 .--- 0- 0 .--- 10-0 1.000 18-8 .692
CCHA .505 5- 5 .500 0-0 .--- 2- 4 .333 0-0 .--- 3-1 .750
ECAC .497 28-10 .737 10-0 1.000 10-10 .500 2-0 1.000 6-0 1.000
MAAC .448 8-20 .286 5-5 .500 0- 2 .000 3-5 .350 0-8 .000
which seems to indicate that MAAC teams will be excluded on the basis of their weak conference and limited non-conference schedule. This means denying a bid to Quinnipiac, who are 14-2-2 against the Division I teams in their conference, but have otherwise only beaten Army and split a pair with Air Force. Neither of these teams has won a single game against a member of one of the four established conferences.
For once the assignment of the eight at-large bids is relatively painless: UNH, BC, CC and SLU win comparisons with everyone else, and DU and OSU are also easy choices. The comparisons among bubble teams stack up like so:
Team lPWR RPI Comps Won
1 Denver U 6 .549 OS__NMNiNtRPPn
2 Ohio State 6 .539 __ MiNMNiNtRPPn
3 Michigan 4 .549 DU__ NM__NtRP__

5 Niagara 3 .477 ____Mi__ Nt__Pn
6 Notre Dame 2 .541 __________ RPPn
7 RPI 2 .529 ________Ni__ Pn
8 Princeton 1 .531 ____Mi________
DU and OSU are at the top of this crop, and even if we toss out the bottom three and constrain the final choice to Michigan, NMU and Niagara, each of whom wins one comparison and loses one against the others, this rock-scissors-papers (RSP) standoff is resolved by going to the Ratings Percentage Index, which leaves the Purple Eagles out of the tournament field. That field has seven Western and only five Eastern teams, so according to the committee's guidelines, we take the bottom team from the West (Northern Michigan, who win no comparisons with any other Western team) and declare them honorary Easterners:
West East
1 North Dakota 5 .656 MSCCMiDUOS | 1 Maine 5 .623 NHCkBCSLNM
2 Mich State 4 .613 CCMiDUOS | 2 New Hampshire 4 .621 CkBCSLNM

5 Denver U 1 .549 ______ OS | 5 St Lawrence 1 .558 ______ NM
6 Ohio State 1 .539 ____Mi__ | 6 Northern Mich 0 .544 ________
North Dakota and Michigan State get the two Western byes on the basis of their pairwise comparisons even if neither of them wins their league tournament. Maine and UNH get the byes in the East, unless Clarkson happens to be the tournament as well as regular season champion of the ECAC, which would entitle them to an automatic bye. Assuming this is not the case (which means that St. Lawrence must have been the ECAC tournament winner for the purposes of this exercise), we move on to the question of which two teams to swap between the Eastern and Western regions. The bottom two teams in the East are St. Lawrence and Northern Michigan, and while keeping Boston College in the East ensures that their potential second-round opponent will be a fellow Hockey East team, it's pretty certain that the committee would place them there anyway for attendance reasons, with the East Regional being held in nearby Worcester, Mass. In the West, the bottom three teams are in a RSP tie, but Michigan has the highest RPI of the three (.5493 vs .5486 for Denver) so they would get the nod to stay in Madison, a decision which seems to be consistent with considerations of both attendance and conference balance. The resulting regions:
West East
1 North Dakota (W) 1 .656 MS | 1 Maine (H) 1 .623 NH
2 Mich State (C) 0 .613 | 2 New Hampshire (H) 0 .621
3 CO College (W) 3 .584 SLMiNM | 3 Clarkson (E) 3 .585 BCDUOS
4 St Lawrence (E) 2 .558 MiNM | 4 Boston Coll (H) 2 .582 DUOS
5 Michigan (C) 1 .549 __ NM | 5 Denver U (W) 1 .549 __ OS
6 Northern Mich (C) 0 .544 ____ | 6 Ohio State (C) 0 .539 ____
have no first-round matchups between conference foes if the regionals are seeded naturally, and the two second-round matchups are unavoidable given seven Western teams and a desire to keep Noston College in the East. The most probably tinkering might be to put NMU in the East in place of DU or OSU, but the Wildcats look like a reasonable Western draw as Marquette is closer to Madison than either Denver or Columbus. This makes the predicted brackets:
5W Michigan (C) 6E Ohio State (C)
4W St Lawrence (E) 3E Clarkson (E)
1W North Dakota (W) --+--2E New Hampshire (H)
|
2W Mich State (C) --+--1E Maine (H)
3W CO College (W) 4E Boston Coll (H)
6W Northern Mich (C) 5E Denver U (W)
