I'm guessing they view ASU much like they were viewing Notre Dame. Doesn't matter if the hockey team is any good, they are perceived to be a "big" school that will have tens of thousands of fans across the country simply because their football team is well known.
However as you pointed out, this flies directly in the face of being a conference that was all about hockey. Someone said that hockey might be only the 3rd biggest sport at ASU but I think it would be lucky to crack the top 5 or even top 10 in terms of what their fans will watch / attend or what will be shown on their TV network. In my estimation:
M Football
M Basketball
W Basketball
W Gymnastics
W Volleyball
M Baseball
W Softball
M Wrestling
W Soccer
M Swimming / Diving
W Swimming / Diving
W Lacrosse
Maybe hockey gets on the list here
Then everything else that gets little or no viewers M/W Cross Country, M/W Golf, M/W Track & Field, W Beach Volleyball, W Waterpolo, W Triathalon, etc.
Some may think this ranking is silly and that hockey couldn't be that low on the list. Well look at how many games the BigTen shows on their network and keep in mind that almost HALF of their member teams actually have hockey programs. Why the heck is ASU's network going to show ASU hockey playing a bunch of schools NOT in their conference and that no one has heard about?
