A guard after you kill your first dragon says about never hearing about Tiber Septim killing any dragons, and another guard says about there not being any dragons then. Paarthurnax says that you have the "Dovah Sos" or Dragonblood, and we are no emperor, so all Dragonborns must have Dragonblood. Miraak, being "The First Dragonborn", proves that other Dragonborns have existed and could shout. My basic point, however, was that The Dragonborn emperors more than likely could shout, but due to the lack of dragon souls (which initially enable the Dragonborn we play as to shout in the first place), it could never be demonstrated by them. That's not proof. And I already said that what Paarthurnax refers to as the dragon blood is not the same as the Imperial Dragon Blood of Tiber Septim. Paarthurnax is referring to the Dragonborn's kinship to the dragons, but the Imperial Dragon Blood is an actual bloodline.

True that this isn't proof, but there is nothing to disprove it either, if there was a dragon and the emporers were unable to absorb it's soul then you would have proof, but as the guards said, "That's because there were no dragons back then idiot."
