Lol, well anyone with eyes can see that you don't know what the hell just happened so all fanfic theories aside.
So this assumption of attention is your answer?
He already said no, so what else use is Crocodile for Doflamingo?
Nothing but to do his job in killing him, which he failed to do.
If he had Haki, he obviously used it and failed.
Doflamingo can't put down Crocodile for sh*t, he's fought Whitebeard too many times to get put down by him.
Well you don't know if he has it or not, but for one thing it takes good Haki toss an admiral to the ground.
No weak Haki like that would make him bleed.
I could say the same to you.
It's not an assumption, seeing as how he called out Crocodile's name and brought up teaming up once again. Doflamingo can choose whether or not he used Haki. The fact that Doflamingo wanted to team up with Crocodile is proof that he didn't use Haki. You have no proof that he did.
Not necessarily. Kuzan wasn't using Haki when Jozu hit him, he was using his ice powers at the time. Meaning, Kuzan's Haki wasn't even activated to negate Jozu's, no negating Haki=Jozu being able to touch Kuzan's body. Jozu was able to knock down Kuzan and make him bleed not because his Haki was super strong, but because, as your small mind has clearly forgotten:
1. Jozu has diamond, the world's hardest material, coating his body
2. Strength to deadlift and throw millions of tons
3. Height about twice as big as Crocodile, at least 16 feet tall, meaning he's weighing well over 500 pounds, most likely even more.
4. Immense speed
It's not because his Haki is super strong, it's because he slammed into Kuzan with the force of over 500 pounds running at immense speed while being coated in Haki, and while Kuzan was unable to use Haki to neutralize his. Anyone with half of a brain can see that.
