Yes.
I already have one with
@Dragon777 though.
In case he has a BB, you guys can decide together.
By the way, you think he forged his own BB?
WB commanders are built different. Top tiers need to put effort to put them down.
Marco and Jozu held their own against admirals too, who were far less restricted than GB/Fuji in Marijois.
Morley << Ivankov, who got low-mid diff by Magellan.
Plus, Mihawk's nature means he plays around. There was no real stake for him in the fight.
While Greenbull wants to protect the CD, hates revos, want to avoid collateral in Marijois.
Why not just go to his base which is supposedly >= Oden, one shot Morley without collaterals?
Anyway, that's just part of the argument against greenbull forging a BB.
Main thing is, dude has no aura. His aura is Saturn level as far as top tiers are concerned, after what happened with Shanks. Can you imagine Oden or Mihawk or even freaking Big Mom react this way to Shanks' conqueror's haki?
If his base is above Oden, dude should be amongst strongest top tier given his DF.
