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.
If that's the case destroy LHW, Middleweight, and welterweight, because Jones, Silva, and GSP in their respective classes destroy all chalengers.
