was the true steel. Stannis is pure iron, black and hard and strong, yes, but brittle, the way iron gets. He’ll break before he bends. And Renly
, that one, he’s copper, bright and shiny, pretty to look at but not worth all that much at the end of the day.
– Donal Noye, to Jon Snow
I defeated your uncle Victarion and his Iron Fleet off Fair Isle, the first time your father crowned himself. I held Storm's End against the power of the Reach for a year, and took Dragonstone from the Targaryens. I smashed Mance Rayder at the Wall, though he had twenty times my numbers. Tell me, turncloak, what battles has the Bastard of Bolton ever won that I should fear him?
– Stannis, to Theon Greyjoy
Stannis by badassery
I can see at some point Renly's men recognize Stannis as the true leader and switch to him.
I can see Stannis don't bend and end up breaked against another more tough opponent... but Renly?
"he’s copper, bright and shiny, pretty to look at but not worth all that much at the end of the day"
He will do some bitch move move before the end, and men will lose respect, specially if they see Stannis will/sacrifice/badassery on the other side
Renly was all about charisma, but not the kind of charisma that work in war times
