What a silly blanket statement. Your logic is so faulty its ridiculous. Just because Ronda dominates her competition doesn't mean there aren't plenty of great WMMA fights and matchups.
That's like saying MMA over the last 15 years ago wasn't compelling because Fedor, Anderson, BJ, GSP, Gomi, Wand, Hughes etc all dominated their respective weight classes.
Ronda has been champ for all of 3 years and had her first pro MMA fight 4 years ago. You guys are way too short sighted.
Royce was unbeatable until the competition caught up as well. That doesn't mean Men's MMA wasn't compelling.
