To be perfectly honest, no one.
But what is the urgency?
Justin is already getting it. And it's not like they are fighting tomorrow, so we have to have someone else after! (Imagine if there are controversies, bad refereeing/judging or an accidental headbutt or eye poke, etc... and now they have to remake it? then what? Islam will be stuck waiting?)
That means there's time for Islam to fight someone else. With full camp.
Dariush will be healthy, DP needs to fight someone...
That's #1, #2 and #3.
I don't think Tony, Chandler or Hooker deserve it. I won't even waste my time on Conor.
RDA IMHO is not deserving as well... I wanted to see where he was against Fiziev, but now he's out... (It will be interesting to see if he fights Islam now, but come on... he's 2-4 in his last 6, inactive for 3 years... again, not the guy to propel you to a title shot)... as much as I love RDA!!
But there's Gillespie who is 14-1, and Mateusz Gamrot who is 20-1 and was a champion at KSW... for whatever this is worth

But they are all good guys climbing up the ladder that makes this division so good and exciting.
I mean, I just run through the top 12, and there are great opportunities here.
If we only concentrate more about the fighters than the belt...
