Certain threads in gambling discussion are rather unique. And it's completely understandable also if they grow into mega threads. It's because they're not discussing a specific game or event or tournament or a similar topic. They're basically covering leagues and sports. You mentioned Premier league. There's also the NBA, La Liga, MMA, ESports, and others. They're general topics. They don't have an end.
That's true take the case of the Crawford - Spence and the Garcia - Davis matches, there are so many things to be discussed because of so much fresh news coming in before the actual fights and the post-fight analysis, the discussions will not just stop after one fighter beat the other fighter, there are still post-fight conferences and what's next on both fighters that when the thread is finally lock everything about the fight and both fighters future have been discussed I'm sure many readers in the internet will find the discussion on boxing not boring, because of the many contradictions and the flow of new information.
