Proof he was not using his usual 'lightspeed'?judging from his nervousness and sweaty self when he said 'Sasuke do not let that hand catch you' I think he was moving more than his usual 'lightspeed' to be honest :lol.
You must be joking. A clear example of Naruto probably moving at lightspeed or higher is when he dodges Madara's
LIGHTbeam. He says that to Sasuke because the hand had absorbing properties and if Sasuke was gone, GG Ninjaverse.
Sakura is tiers below Naruto and Sasuke. Just be happy with the fact Kishimoto actualy gave her the spotlight a few times. Sakura fans complain that she was badly written and not well used when it is clearly shown that she was important to help Naruto survive and seal Kaguya, or when her strength was shown while punching juubi minions during the war arc.
She was praised by other characters plenty of times, idk what the hell you guys want more but she is NOT on the same level as Naruto, not even the best of fanfics can make it sound good.
Just be glad with what she was given by the author because honestly and due to her annoying perfomance during the whole series, she actually deserved zero.
Sakura chan.. fml
