I'll try to behave...
Frankly time. I only did the major conference (ECACNE and MASCAC are primarily not contenders)
uscho.com, collegehockeystats.net, Excel 2010, some vlookup functions, and a few adding and subtracting. Figure out all the NC games all the teams played, find all the NC games they won, add up all their win% and divide by number of teams games. Sometime I will sit down and do the Loses and Ties, but that's where it is now. Granted things could change big time in the upcoming weeks still. I also want to do one that factors in SOS as well. A 13-4-1 ECACNE team probably isn't the same as playing a 13-4-1 ECAC West team. Teams like Canton are probably killing the SUNYAC SOS and the same with Aurora out West. Could I have missed a few, screwed up a number here or there? Sure. (Keep in mind I did not count the MIAC showcase games for the MIAC or any other conf vs conf NC matchups)
I was really shocked at the WIAC that it was that low. However when 12 of your wins are against Aurora, Finlandia, and Bethel it kills your win%. The ECAC West, while not having a ton of below .250 (3 I believe), doesn't have too many above .550 teams (4 I believe) in their win column either. The ECAC West is the one league that could really move up and down more so as they have a ton hovering right around the .500 mark.
Not a direct poke at the West. Just pointing out that while the ECAC West may have the best inter conference record, its not just how many wins but yet who they are coming against. Believe me, you can put Plattsburgh in that category as well, granted a starting goaltender injury (and a coach who was trying to figure out who his #1 was) play a part in it, come selection Sunday there are currently enough more deserving teams to grab a Pool C bid then Plattsburgh based on their criteria. Had Plattsburgh taken out Middlebury, Williams, and Geneseo even 2 more loses to Oswego they would still be in decent shape come NCAA time. Plattsburgh loses a lot of common opponent games with those 3 loses alone.
