Real boxing fans wouldn't care. Only casual fans care about knockouts, the real fans are more interested in technique. Its not the same on MTF here, people have a very immature mindset towards tennis.
there are fans of pretty much every player and every style on these forums
. Just because they see things differently from the way you see them, doesnt make their mindset immature. Also, I'm getting abit tired of people claiming that there are "real fans" of any sport, and ofcourse telling others what those "real fans" prefer.
So to add some nuance here. I prefer to watch attacking tennis, because I like it when players take risks. I can also appreciate good tactics on court though. I just don't like it when players keep the ball in play with the sole reason of hoping to draw errors from their opponent.
