I think so as well.

Given that people like Oden or Big Mom can be born extremely powerful and it's not that implausible that Dragon's a real powerhouse, they could be the same character.

Dragon/Rocks would have been born a monster, been able to kick serious ass at a very young age, and either convinced or beat up every major pirate out there in the day to join him. (And he could have simply convinced many of them! Whitebeard had a legitimate grudge against the world nobles, Big Mom might have seen it as a way to build the society she felt Carmel wanted to create etc. (And some others might have simply joined because this seemed to be the crew to be on.)

Now Roger and Garp didn't (And in case of Garp) still don't like the world nobles. So whilst Rock/Dragon might have been a legitimate threat to the world, neither wanted to actually kill him. So instead given that Roger was aware of the Poneglyphs, perhaps Roger said that Rocks actually couldn't have won. Because he couldn't hear the voice of all things and that's necessary to defeat final boss Im. And Garp decided to give Rocks a fake identity as his 'son'.

The rest of the crew, not liking eachother disbanded. (With some like Kaido being captured, leading to his set of failed executions and eventual escape.) And Rocks, now Dragon, decided to still plan a revolution, but in a kinder, gentler, wiser way. Whilst trying to find someone who COULD hear the voice of all things. (Which he might currently presume to be Sabo.)

Also if Rocks age of 17 seems to low... Luffy is currently 19 and was 17 before the timeskip. And Whilst Luffy was kicking all sorts of Warlord and Lucci asses even before the timeskip Luffy wasn't even born a monster like say an Oden or Big Mom. So let's say Rocks/Dragon WAS born like that, it's not so improbably he could do amazing feats even two years younger then Luffy.
