jiraya was killed by the pains so he doesnt count, team guy wouldnt make a difference nor would yamato and anko at the end of the day the village would still have been destroyd by st...btw i think 3 giant toads+2 toad sages+ Sm naruto+ intel+plot+kyuubi outbreak > team guy+yamato and ankoKonoha was caught by surprise. With most of their ninjas unavailable and bad organisation skills all they really had time to do was protect civilian casualties (Sakura, Shikamaru), get the research from Shiho and Tsunade to protect all the villagers.
If Kakashi had gotten more backup or had gone in with Guy things could've seriously gone differently.
Danzo and his whole unit of elite ninjas refused to fight.
Yamato, Sai & Anko were away.
Team Guy were off on a mission.
Jiraiya was dead.
Naruto was at Mt. Myoboku.
They got trashed but with better organisation and better numbers I think that even without Naruto the Leaf IMO could've defeated Pain.
