Am I really though?
The flute girl
Sakura has high resistance to gen jutsu, but so did Shikamaru, so she would activate her yinseal disrupt her chakra and break free...She done fore.
The spider guy
Katsuyu can solo him, a giant slug vs a spider. Really, Sakura isn't as restricted as neji was either. She can punch the ground to throw him off balance and he has no tree to hide in or anything.
The fat one.
It's basically Sakura vs Choji (but Choji is stronger than this guy now), she can defeat him mid diffculty, and kill him before he even has the chance to summon that pillar thingy.
The two head one
Sakura and Katsuyu will burn him with acid because she doesn't have any use for engaging in physical combat with him. And if worst comes to wrost Sakura staps the head and heals herself, she has the will power and skill look at Sasori fight.
