I found nhl66.ir was good for streaming games. I stopped my premier player subscription a while ago as they never had the games I wanted to watch.
I'm not sure how they work media blackouts in the UK, I know it used to be games that clashed with premier player, but if they don't have it any more who knows? https://nhllive.com/en/api-status/blackout looks like you can look up which games you can get in your region here, but they haven't updated it yet 😅 I think you also get access to previous games on NHL.tv which is a bonus.
I'm just looking forward to being in the right time zone for once 😍😍 even if Crosby, Malkin & Guentzel are all out already 🙃🙃 classic Pens 🥲
