The reorganization of existing teams into new conferences may lead to the growth of D1 college hockey, but I'm not sure how? If college hockey doesn't grow it will become an increasingly minor and provincial sport, although this would suit some fans just fine. If you're one of them, stop here.
I believe expanding college hockey's fan base is the critical element in the growth of college hockey. A number of things could contribute to expanding the fan base, including bigger rinks, more games, a longer season, more teams, better parking, etc. - but I believe more access to watching college hockey is the key to its growth. I believe a deliberate and concentrated effort to seek increased TV coverage of college hockey is by far the most effective initiative that the NCAA, conferences, teams, and fans can make - even if it produces no immediate financial rewards.
