HW has some excellent fighters, mainly Cain, JDS, Werdum, Cormier and Bigfoot.
The problem is that the excellent fighters are too far ahead of the rest of the pack. In the last five years, they only have a single loss between them that was not inflicted by one of the others.
Cormier is dropping to LHW. With Cain being the champion, that leaves three fighters who can earn title shots without favourable matchmaking. Of those, only Werdum hasn't fought Cain yet.
So, unless the top of the division is injected with fresh blood, the next few years of HW title and top contender fights will involve these guys fighting each other, and/or undeserving lower rankers being given title shots for the sake of variety.
