Nobody. They should abolish the entire division.
But in all seriousness, LHW is the worst division out there right now aside from Flyweight. The only fighter that comes close to being a legitimate contender right now is Gustaffson. And he'll get humiliated if he ever fights Jones.
Pretty much this, the real problem is that Jones is just that much better than everyone else. Cormier dropping will change things and that's about it.
