What's the best way to access live sports?

So, I've used different sites like soccerbite or nflbite but I spend half the game trying to find a stream that doesn't freeze every 5 seconds and require a browser reload. Is there anything as sophisticated as the *arr suite for live sports? I'm assuming an iptv set up is the solve but I don't know where to start looking there and if I can integrate it into my system or if it lives in isolation.
