krieger, its not about them not being as good of fighters as ufc fighters. most of them are not. the points are that other leagues should exist because we, the fans and the fighters need options. ufc cannot hold all the fighters in and it also cant satisfy everybodies taste.
now, all the middle of the echelon fighters that wont make it to the ufc will be pretty much out of options. although they might not be the best in the world, different rules and atmosphere allow them to put on some exciting fights that all could enjoy. in every other sport, if they dont make it to the big leagues, athletes have places to go and earn a living and put on some great performances.
