ESPN/ABC is only doing 25 regular-season games which are roughly once a week. Turner is doing up to 72 which brings us to 97.
Then we have the 75 ESPN-produced national regular-season games that will be streamed on ESPN+ and Hulu which will be exclusive.
For a US hockey fan subscribing to ESPN+ will become essential but they will also have the games that were formerly on NHL.tv. Center Ice in the US
I thought I saw a quote that Center Ice (the tv package) will still exist. But NHL.to is gone and I can’t imagine the exclusive Hulu games will be available on Center Ice.
My best guess on how the TV situation shakes out is the ESPN linear games (15 on ESPN, 10 on ABC) will be post January only. ESPN on Thursday Nights (beginning after the NFL’s Thursday Games end and Saturday afternoons on ABC.
TNT will have one night for the entirety of the regular season with double headers. They may open a second night in TBS post-January for single header games. Also, a few special nights of coverage on TNT (like a Black Friday triple header, an extra night of coverage in the lead up to the Winter Classic post-Christmas, and final night of the regular season). My best guess is Wednesday Night for the main TNT coverage (if they can get AEW resolved), and Sunday or Monday Night for the late season TBS.
Hulu my guess will be Tuesday Nights and Thursday Nights pre-ESPN linear coverage. Plus probably whichever late season night (Sunday or Monday) that Turner doesn’t take for the second night. A few Friday/Saturday games as well to round out their schedule.
NHL Network will likely fill in any gaps assuming it stays around (which sounds like the plan).
Basically every night of the week will be covered by a national rights holder. That said although ESPN is the primary rights holder, for a traditional tv viewer it will feel like Turner will be as they will have full season coverage.
