no matter what pain said, the fight told a different story. jiraya was destroyed just in melee against the 6 and had to trick 3 of the weak paths to even kill them. sage naruto wasnt beaten, it was normal naruto, and sage naruto could well fight the five of the paths and killed many of them in melee, something jiraya didnt even after getting to know about the rinnegan-link.When jiraiya fought pain, pain himself said jiraiya himself would have defeated him had he had some intel on him, while on the other hand naruto had full intel, pain was not fighting with intent to kill, hinata interfered which triggered the 9 tails which was the only reason naruto beat deva path.
Jirayias speed isn't his most impressive trait, while in sage mode I believe he can definitely dodge amaterasu, he might not be able to dodge susanoos arrow, however he does have more than one barrier technique as well as many earth style techniques he could potentially use to block. However danzo was able to avoid the arrows and I don't believe him to be as strong as jiraiya.
Sasukes chidori is not strong enough to deflect one of jirayias gigantic rasengans, and just bekiraiya uses oil in combination with his fire techs in order to power them up, and sasukes lightning has an advantage over earth but it doesn't mean it can block any eartj style attack.
why should he be able to dodge amaterasu if sasuke can see him? if sasuke potentially is even faster than him? you can only dodge amaterasu if you are to fast for sasuke's sharingan.
the only thing where danzo is really strong is in taking blows. and to be honest i think that danzo would have been a really tough match for jiraya. izanagi is just insane. apart from that the huge super fast mokuton-wall wasnt enough to completely block the arrow, i doubt that some little earth-walls could do it.
i havent seen any strong earth jutsu by jiraya at all, so if sasuke is able to completely neutralize deideira's variable clay, i doubt that jiraya can hit him with something like that.
ever tried to fight with a stone against an enemy who can predict movements and uses a spear? even with a huge stone that wont work. apart from that the moment jiraya charges at sasuke with a melee-attack it's the invitation to use amaterasu or susano'o.
