I’m just addressing the theory you present - nothing specific to DA
I disagree with your contention that public speaking (esp to media) is a barometer of leadership
Leading a locker room is a different animal than addressing a room of reporters- completely different context
There are plenty of teachers who are super capable in front on their classroom who then lose all confidence when they address an assembly
In the locker room you’re a strategist and motivator
In front on the media you’re a politician
Vastly different things
