How is there no proof of this when Whis explicitly says he doesn't know of a mortal stronger than Goku and Vegeta even though he FOUGHT Broly ???
Are you also gonna deny that Granolah > Broly even though Granolah appears in Whis's crystal ball when he searches for the strongest in the universe...
And? He isn't talking about Broly Arc Goku and Vegeta.
Current Goku and Vegeta > Broly.
Considering this isn't written by Toriyama I disagree.
Only the Beerus statements shouldn't be taken seriously because Beerus will ALWAYS be retconned to be > Goku/latest villain
Granolah>Goku and Vegeta is established
Then when Goku asks Whis if he knows of a mortal stronger then they are he replies that he doesn't.
Remember thar DBS Broly is canon so Whis fought Broly and witnessed his strength yet he still says he doesn't know of a mortal above them
