I cut cable last year but care enough about sports and particularly college basketball that I spend the 25 a month for sling tv and access to all the ESPN channels (except classic) plus ESPN3. I got TNT TBS and Tru TV as well on it, plus many stations I never watch. But I may cut it off till September, if I decide I really don't need to watch the French Open, Wimbeldon and the handful of games the Mets will play on ESPN, and just get it around baseball playoff time, and maybe for the US Open too.
Casual fans of college basketball who don't have cable and don't really follow sports in general don't care if they can't watch ESPN all year round. If they want to see the final four and it's not available at home, they'll go to a bar or a friend's house to watch it.
