There are different reports, with Sinclair (which is a fundamentally dishonest company) claiming it is not shutting down, but rather is going to "partner" with Campus Insiders to produce the content which will be shown on both the .2 ASN network and on as "over the top" on Campus Insiders pay site. Others are reporting that the "linear" .2 ASN network will shut down and Campus Insiders will buy/be given their remaining contracts only for Campus Insiders. It is certain that Sinclair fired everybody in the building who worked for ASN.
IMHO, ASN's coverage was fine. OTA, it was in SD, but it was OK. You could tell that the announcers were calling the games off the feed rather than actually being at the venue, but bigger outfits have done that. In my area they would take some Marshall (local team) content and move it to the .1 channel pre empting then major network in HD and it was fine.
The network was hurt by not being on DirecTV. Sinclair should have demanded it in return for retrans of its major network affiliates. My local hangout has lots of Marshall fans and they just could not show the games. They could put up an antenna, but just didn't. Landlord issues.
But the main point, IMHO, was the sports on it just were of little interest other than to fans of that particular team. In a world where there are 20 or 30 other games on, nobody is going to make an effort to see CUSA, MWC, or I-AA games in SD other than their own fans.
