Just a couple of comments from a current CCHA..soon to be BTHC observer.
First...I don't see any possibility that any HE team would leave for the west.
Second, it looks like Notre Dame is the key to this. Notre Dame has three choices and the choice they make will likely determine how the rest will fall.
One choice is to stay put. If they do they maintain a league where they can bus to most games instead of fly. They also have a league in which along with Miami they will have an excellent chance to make it to the NCAA every year. The downside is TV interest in the CCHA will certainly be down along with revenue. Currently Fox Sports Detroit is an unofficial UM/MSU network because that is where the advertiser interest is. Almost all games they televise involve one of those teams...and most are after the end of the football season. While UM/MSU will certainly schedule some road games against CCHA opponents, they would mostly be during the first part of the year when Fox Sports Detroit would have little interest in televising college hockey. By January they'd be stuck with Miami vs Ferris State which wouldn't be much of a draw in their core viewing area.
The second choice is to form a new conference with North Dakota, Denver, Miami, WMU, UNO, CC, and UMD. This would mean flying to most games. To make up for the increased costs they would need to generate more revenue. Could the new league secure a good TV package? CBS College Sports is probably the only network that might be interested...and I'm not sure how much they would be willing to pay for the rights.
The downside of this option is that Notre Dame is less likely to make it to the NCAA as it would be much harder to have a winning record in the new super conference. In a conference of the best of the rest of the west, probably only about 2 or 3 would make it to the big show each year.
The other downside is a likely decrease in the number of D-I teams which in turn could decrease the tourney from 16 to 12 teams (or maybe even 8). This would severely impact the number of at-large bids.
The remaining not-good-enough for the new super conference schools would be the St. Clouds, MTU, Lake States, and Ferris States. They would likely band together to form a new conference. In the process, it's unlikely for financial reasons they would invite the Alaska schools or Alabama. Let's assume that the leftover teams (excluding Alaska) were: BSU, MSU, SCSU and MTU from the current WCHA and BG, FSU, LSSU, and NMU from the current CCHA. They could have a 20 game schedule by playing their own division 4 times and the opposite 2 times. This would mean two bus trips to the other division each year. They could try to schedule the remaining games against the BT or the new super conference. (BT will only have a 20 game schedule, so it could work.) Without a conference, I can't see the three outlier teams making it as independents. It's also unlikely TV would have much interest in this league. With less income and exposure a couple could fold in a few years.
The third choice would be for Notre Dame to join HE. If they did, I'd expect Miami to join at the same time (or alternately join the WCHA). The WCHA would still be pretty strong, however, it's likely the CCHA couldn't survive and would need to merge with the WCHA or fold. Even with a merger a few teams might decide to drop hockey. There also would be no guarantee UAH would be invited to join.
As I said at the top...I really see this as a Notre Dame decision. What they decide will dictate the direction other schools go....and with it the future of college hockey.
