This is completely false. Go out East for a week in the winter, and the local Fox Sports Nets won't have meaningless tv on, they'll have college hockey day in and day out.
The market for it out in the midwest just isnt big enough, but with the emergence of Michigan, Michigan St, Minnesota, Ohio St all having solid college hockey teams, things might change down the road.
With that being said, College Baseball gets nothing, zero coverage and it really makes for a lesser type of a game. I used to be a NU baseball season ticket holder but because I had no clue who the players were, you had no idea who was a senior, junior etc, and other things I just stopped following and stopped purchasing season tickets.
College baseball has a market, but until some television network takes a chance on it, theres going to be no college baseball market, and ultimately be no MLB draft.
