With all the stupid teams Bettman brought in, I can not say that any of the California teams should fold. San Jose is a profitable franchise that sells out 99% of the time, and the state of California are investing in many hockey programs for younger kids to get into the sport.
Columbus is another great move, is that the team needs more of a fan support. I think it was more logical to put a hockey team there, instead of Cincinnati or Cleveland, because no one would go to those games when you have the Cavs, Bengals, Browns, Indians, and College sports to go to. Columbus has nothing to offer, and its good for them to get a team.
Having a team not in Minnesota is like having a team not in Ontario. That was another good move that Bettman made.
Though Bettman should have invested a team in Eastern Canada, so they aren't neglected.
