What makes you think that Susanoo can't break out of a A rank technique, who's size and depth is determened by the users chakra and skill.
- Underworld swamp technique (Naruto Wikia)
(By changing the surface of an object beneath an enemy into mud and creating a swamp, the user can sink his enemy into the mud. The adhesive, chakra-infused mud ensnares the enemy's body, making it almost impossible to recover one's strength and escape from the swamp. The size and depth of the created swamp depends on the user's skill and the amount of chakra used, but if the user is an expert in this technique, it will always be possible to make a fair-sized swamp which is extremely effective against a great number of enemies or when having to face gigantic creatures.)
lets not forget about the size that Susanoo can reach.

even if somehow the susanoo did start to sink into the mud, it would be too slow and it would take no effort to jump out of the head of susanoo to a safe area.
dont be foolish thinking a average A rank technique could trouble the Susanoo Gods.
I hope for your sake you never get stuck in quicksand. You will reach china pretty quickly from where you are with that logic. Do you also survive by using wet matches?
The more you struggle, the more you sink
A bottomless swamp from Hell!!
By changing the ground into mud and creating a swamp, the enemy is sunk deep underground...!! The adhesive, chakra-infused mud ensnares the enemy's body. It's impossible to recover one's strength and escape from there.

When fighting a great number of enemies or having to face gigantic creatures, this is an extremely effective technique.
↓The giant snake captured in this bog is prevented from moving! But if you ask Jiraiya, he'd say it is insufficient. The real goal of this technique is to completely submerge the target underground.
[picture of Orochimaru's snake summon caught in this technique]
As the Databook and Manga both showed, it a technique very effective against large targets, even giant snake summons (which btw are bigger than ms itachi or ms sasuke's susanoos) couldnt muster enough strength to come out of it
and on top of it, it was a weak yomi numa as jiraiya says [

], so you cannot simply fight your way out of it
The databook also further goes to say that it is also very effective against a large number of enemies, meaning even humans will fall prey to this jutsu

As seen here
-human path got instantly caught and was simply unable to move or escape by the "gathering chakra to your feet" method as some fans suggest
-animal path avoided contact with yomi numa and instead clung to human path rather than stand on yomi numa by "gathering chakra on his feet" (note nagato had full knowledge about jiraiya's jutsus [

])
-jiraiya himself was pretty confident about trapping human path
I believe the perfect susanoo would be able to escape because of it's massive size and the fact that it has legs. Other forms probably wouldn't do so well.
