I live in Northern Indiana currently. I was born in StL (Barnes Jewish). When a buddy showed me NHL '93 on the genesis in High School (I'm old), I picked the Blues because I was born there. As I became a fan of the sport through the game, they stayed my team. This was further reinforced when I went to grad school at Wash U in StL and attended several live games during that time. So that is why I started cheering for the Blues as opposed to Hawks/Wings which is more common in my area.
Fox Sports Indiana is a subset of Fox Sports Midwest. Indiana based events get priority, mainly the Pacers but sometimes college sports as well. Otherwise they air the Blues games when there is not an Indiana event. I get roughly half the games/post-games aired in this way. This is vastly preferred as I like to DVR the game, start watching late, fast forward through breaks and intermissions and heavily rewind to break down plays. In the event of conflicts, all games are available to me on Fox sports Go (aside from NBCSN/NHL Network ones) or on FSMW2. However, FSMW2 is not available in HD, and hence borderline torture for me to watch in a heavily bordered 30-inch window within my 65" 4k TV. I actually found it much easier when I lived in Florida. I just bought NHL GameCenter or Center Ice. But since it is technically being aired in Indiana (albeit in a laggy app or 8-bit graphic quality picture), those services black out Blues games for me when living in Indiana. I'd gladly pay the money for one consistent and high quality place to watch 90% of Blues games, but its stupidly just not available to me here.
As for news/analysis, I mostly get my info through here. I like the stat sites (natural stat trick, sporting charts, NHL.com) as I'm sure many have noticed. I'll also randomly google "Blues (trade rumors, news, injury update)" and peruse other sites when I am bored. But as OP said, the coverage is generally heavily lacking. At those times, I prefer rumor aggregation sites as opposed to amateur analysis. They are generally crap, but they generally link to the source material of industry insiders.
