I have personally enjoyed watching it more recently, even though I think right now Tyson Fury is doing the same thing as the Klitschkos did , I mean why would he pick Otto Wallin as an opponent, that's cherry picking at it's finest. Even though I have to say the fight was better than I expected.
I think Joshua and Ruiz attracted a lot of attention to boxing with the first fight , heard people talk about it who weren't even interested in boxing before so if they give us a good fight in December that would help a lot to gain some attention to boxing again and get more people interested.
About the YouTubers you mentioned , well they'll have a rematch in Novemeber which will gain some attention because they have around 20 million subscribers I think. And even though I at first didn't like the idea of it a lot, it makes sense, most of the viewers probably have never watched a boxing match before and that's the only way they could get interested in it.
