This is the conclusion I've come to as well. To get CBS Sports Network, seems you need to have cable or one of the more expensive (ie (the ones that are $65/month or thereabouts) streaming subscriptions like Fubo, Hulu's Live TV package, Sling etc. And
@ChrisWoods it does look like your YouTube TV should include it.
So for those of us who previously had ESPN+, which had Rangers on most weeks last season, this move to Paramount+ isn't looking great based on the league schedule released so far. P+ still the place to follow our European games of course. Reckon I might be looking at RTV for the league games though. Expensive compared with ESPN+ and P+, but a bargain compared with what I'd need to spend to get cable, Fubo etc.
