The major problem at this stage is the lack of fights that can be made which are exciting - even to hardcore fans. There isn't much that is interesting. And there is nothing out there which is mouthwatering.
Johnson has beaten everyone.
Lineker has evacuated the division because he can't make weight.
Dodson has evacuated the division - and never fought Benavidez, a brilliant match up.
Benavidez beats everyone except DJ and Cruz, but there are no 'wow' matches out there for him.
There are some solid prospects, people like Scoggins, and guys like Horiguchi and Cejudo who can get better, but, basically, four years in, the FLW division isn't all that exciting.
That doesn't mean that the division should be canned as some people assert; too much work has gone in to it now (however, I do think it should never have been added in 2012 - it was probably half a decade premature to create FLW) . It just means that the sport is still growing and deepening. The future will most likely be great. In boxing, people of this size fight at super bantamweight, featherweight and super featherweight. Those bouts are often awesome. Hardcores get excited by those divisions. It will happen in MMA. But FLW was created prematurely. That's the bottom line.
