I think that there's a chance that Sabo might be stronger. Sabo and Ace were always neck and neck strength wise when they were kids so assuming that Sabo progressed as much as Ace did isn't unlikely. And pre time skip Ace was significantly stronger than everyone on BB's crew except for BB.

Very true, The thing is BB being a Yonko now and his hunt for powerful DF users might give them (his crew) the edge. I think Burgess is DF free however, he was strong, just Ace was alot stronger. Sabo imo should be close to luffy's level. I dont know though, he can definitely be stronger as looking at the current events he has to be = to luffy if not stronger to win!

Pretty much this. It's not far fetched if the growth rate was consistent and considering how long he's spent with Dragon and the revolutionaries. Burgess just seems like the perfect hype tool for Sabo with the BB/Ace links.

No crew's user showed what the two years made to them... Luffy barelly showed how he dominated the Haki... and DoFamingo powers didn't work without The Power Of The Cloud.

We've seen enough to know that his crew is still no where near Admiral level and Doflamingo is. Doflamingo beat Smoker, Sanji and Law effortlessly. There's no way Luffy can win a straight up fight. Unless Doflamingo gets super trolled, which might happen since Luffy managed to beat Crocodile and Enel even though both were a lot stronger, but I don't think he'll beat Doflamingo yet. 

I don't think Doffy's quite at Admiral level either. Law was fatigued from running hax across the Punk Hazard Arc, as i imagine he could have put up more of a fight (not won, but not lost as badly as he did) otherwise.

The Crocodile analogy is a good point (or perhaps Moria), someone who is definitely stronger, but can be outfought through a combination of smart tactics and sheer gumption.

Yeah, Doflamingo being Admiral level is debatable and I do think that he's in the lower end of the tier. We saw Doflamingo's confidence in the Marineford arc. He was toying with Jozu who gave Aokiji a good fight. Also when he was confronted by Aokiji recently even though he did retreat it was more of a "It isn't worth fighting Kuzan" rather than an "I need to leave before he kills me" so that to me implies that he wasn't very threatend by Kuzan, but for the record I think that Kuzan would have kicked his ass. :p

It's also possible that Doflamingo is a legendary bullshitter (which isn't to say that he brags and can't back it up, but more that he excels at throwing out false emotional signals). He likely *was* scared of Kuzan, but didn't want to show it, like how he showed anger towards Law's demands, when in reality he had the situation well in hand. He is indeed a big threat, but where is power stops is hard to tell because you can never know when he's "serious."

Yup, let's ready ourselves for all the sweet One Piece sauce coming our way!!!:)

I always believed that Sabo was still alive, ever since the chapter where Dragon came back to his crew with someone heavily injured (who I assumed was Sabo). As for the Mera Mera no Mi, I initally thought that Rebecca would end up with the devil fruit, but now I'm not sure what to think anymore with Sabo and the revolutionaries arrival.  It's also good to see Koala again and all grown up. Overall, this arc has been incredible due to all of the surprising and escalating developments.
