NCAA Division I men's hockey realignment of the 2010's

Formation of the Big Ten Hockey conference

The impetus for the realignment was put in motion in September 2010, when oil and natural gas magnate Terry Pegula and his wife Kim donated $88 million to establish Division I men's and women's hockey programs at Penn State University. This gave the Big Ten Conference, at the time a Division I non-hockey conference, six members that had men's ice hockey competing at the D-I level. The specific membership number was critical for two reasons. First, Big Ten bylaws state that the conference may sponsor a sport once six schools have varsity teams. More importantly, this is also the same number of members required for a conference's champion to receive an automatic bid to the NCAA Men's Division I hockey Championship tournament. The conference members voted to add men's ice hockey as a conference sponsored sport in March 2011.  The start date of the hockey was announced for the 2013-14 academic year.

The result of the establishment of the league led to the folowing changes:

• Penn State University started playing D-I hockey as an independent for the 2012-13 season and joined the Big Ten for the 2013-14 season.

• The University of Wisconsin and the University of Minnesota would leave the Western Collegiate Hockey Association.
• The University of Michigan, Michigan State University and Ohio State University would leave the Central Collegiate Hockey Association.

Fallout from Formation of Big Ten Hockey conference

• The National Collegiate Hockey Conference was founded July 13, 2011.  The founding six members are Colorado College, University of Denver, Miami University (Ohio), University of Minnesota-Duluth, University of Nebraska-Omaha, and University of North Dakota. 
• This resulted in the Western Collegiate Hockey Association losing five members (Colorado College, the University of Denver, the University of Minnesota-Duluth, the University of Nebraska-Omaha, and the University of North Dakota), dropping to five members; one below the membership level to gain an automatic birth in the NCAA tournament. To rectify this the WCHA invited six of the remaining members of the Central Collegiate Hockey Association to join the WCHA.  At this point, the CCHA was down to 7 members (the University of Notre Dame, Western Michigan University, Ferris State University, the University of Alaska-Fairbanks, Lake Superior State University, Bowling Green State University, and Northern Michigan University.
• St. Cloud State (then a WCHA member) and Western Michigan University (then a CCHA member) were invited to join the National Collegiate Hockey Conference in the autumn of 2011.  Both schools accepted the invitations and further reducing both the CCHA and WCHA by one more member.
• Ferris State University, the University of Alaska-Fairbanks, Lake Superior State University, Bowling Green State University, and Northern Michigan University all accepted invitations to join the WCHA, making it a nine team league.
• The University of Notre Dame accepted an invitation to join Hockey East, making it an eleven team league
• On January 17, 2013, the University of Alabama in Huntsville accepted an invitation to join the WCHA, starting with the 2013-14 season after previously playing as a Division I independent since the 2010-11 season.  This now gave the WCHA 10 members.
• Hockey East, now being at 11 members, was facing a scheduling issue for league play with the odd number of teams, entered into talks with the University of Connecticut to join the league from the Atlantic Hockey Association.  The women's program was already playing in Hockey East. On June 21, 2012 the school accepted the league's invitation to join the league starting with the 2014-15 season.  The school was planning on playing its conference games at the XL Center in Hartford, which already hosts the school's men's and women's basketball teams, until the facilities for the schools hockey team can be upgraded.  They will still play non conference home games at the Mark Edward Freitas Ice Forum on the schools campus in Storrs, Connecticut.
• The only men's Division I conference left unaffected by all of the realignment was the ECAC.

The final results of the realignment

• The Big Ten Conference was formed to start play with the start of the 2013-14 Big Ten Season with six teams.
• The National Collegiate Hockey Conference was formed to start play for the 2013-14 NCHC Season with 8 teams.
• The CCHA was dissolved after playing from 1971 to 2013.

• Hockey East expanded to 11 teams for the 2013-14 season and to 12 teams for 2014-15.
• The Western Collegiate Hockey Association would now have 10 men's teams for the 2013-14 season.
• Atlantic Hockey would drop by one team for the 2014-15 season.
• The only men's Division I conference left unaffected by all of the realignment was the ECAC.
• A total of 21 (out of 59 D-I) programs are in new conferences for the 2013-14 season and a 22nd  will change conferences for the 2014-15 season.
• Only Michigan Tech along with the founding members of Hockey East (Boston College, Boston University, UMass-Lowell, Maine, New Hampshire, and Providence College) have been in the same conference continuously since at least 1988 and all seven of the these schools joined their present conferences for the 1984-85 season.  So no school has been in their conference more than 30 seasons as of the end of the 2013-14 season

Strangely, with all these moves in the men's leagues, the only changes to the women's Division I leagues were that College Hockey America (which only sponsors a women's league) would lose Niagara, which was droping the sport and added Penn State, Lindenwood, and Rochester Institute of Technology.  The Big Ten only has 4 schools participating in women's varsity hockey (Minnesota, Ohio State, Penn State, and Wisconsin) and the CCHA never sponsored women's hockey in its history as Ohio State was the only member with a women's varsity program and they played in the WCHA
