Just FYI, the official way to watch after the fact isn't Sunday ticket. It's NFL+, and removes commercials from the main broadcast, along with providing an abbreviated version that cuts out all the between play stuff but keeps all the action, and access to the film, and is (in the US) $100, not as expensive as Sunday ticket. You can also search for specific plays by specific players with NFL Pro. (Edit: it looks like they still call it gamepass internationally, and you also get the games live).
Doesn't mean don't look for alternatives, but it's not as expensive as you're thinking unless you want live games.
