Law was supposed to die from amber lead poisoning at the age of 13, and in today's chapter he said he only had one more year left, so he was 12 at the time. He is currently 26, so the events of todays chapter happened 14 years ago.
Sengoku is still just an Admiral in today's chapter, which was 14 years ago. Zephyr retired from being an Admiral and became an instructor at the age of 41, and he was 74 in Film Z. So that means that 14 years ago, when he was 60, he was still an instructor. This means that there would only be two admirals at the time, and there are supposed to be three. I believe that Dragon was the 3rd Admiral fourteen years ago.
Also, if the unknown 3rd Admiral, from the generation of Admirals before the Pre-TS Admirals, was also retired at this time(we don't know if he was still active or not fourteen years ago) then I believe that Akainu filled in his position.
These are the two ways I see how it would be for the generation of Admirals previous to the Pre-TS Admirals
Sengoku
3rd Admiral
Dragon
OR
Sengoku
Dragon
Akainu
One more thing, in the photo below you can see a picture from the Z Film colorspread of all the Marines, you can see Corazon, and he was just recently revealed to be a Marine
On this photo of all the Marines, you can see that immediately to Kizaru's left(your right) there is a guy who's chin and hair looks a lot like Kuma's, and right next to Kuma is a guy that looks like Dragon.
