sakuras isn't a mere shinobi
look at these i found somewhere:
1.only sakura and other highly skilled ninja were able to notice the genjutsu,
and counter it with a powerful enough kai jutsu)
2.she may lack a huge amount of jutsuu's, but she can control her chakra more precisely than even kakashi, and can control it to make huge punch's and kicks n c generally have less jutsus coz c dont name it.
3.Gouwan (Strong Arm; her super strength)
4.Dokunuki no Jutsu: Poison Extraction Technique
5.Bunshin no Jutsu
6.Kawarimi no Jutsu

so c can stand a chance na!
