No he just didn't move and even if he did no one can disregard the fact that he had an immobilizing chakra receiver going through his head and still being able to spit out water bullets powerful enough for Madara to activate his Susanoo armor
He used so much chakra that he basically had no chakra when he got stabbed.
Used seal for Kushina
Used shunshin to save Naruto...then FTG from bombs....then shunshin away.
FTG to a place to put Naruto
FTG to save Kushina from getting crushed
shunshin in a tree
FTG away to put Kushina where Naruto is
FTG 2 and rasengan plus contract seal from Obito
T/S Barrier a TBB away from him
summoned cheif toad
FTG the fox away
FTG himself away from the fox second TBB into the forest and FTG Kushina and Naruto there as well
Summon RDS God
Him and Kushina got stabbed
talked for a long time while stabbed
Minato uses RDS on himself/the fox
Then finally used 8 trigram seal on Naruto, Kushina, and himself to meet Naruto
He did that all in one day less than 24 hrs.
Also Tobirama being able to summon spit when he's not alive is bs plot jutsu. Its not even logical Naruto wise xD
He's still a G but Minato is the OG.
