MMA has never been bigger.
May I ask how old you are, and have you ever been a fan of boxing OP? I’d genuinely like to know because I can never understand why people bring this up.
MMA has never been bigger, it has never been as widely accepted as a legitimate sport, it has never been as much a part of the mainstream as it is now.
Will it still be so in 5 years? Maybe, maybe not. But the fact is that the popularity of any sport, but especially combat sports, is constantly fluctuating. It goes up and down depending on stars, TV coverage etc.
Whether it’s an up year or down year, MMA isn’t going anywhere.
