ok so maybe they wouldnt get owned per-say. However, even if they were able to fight one-on-one and come out even, Kakashi and Gai are still in a losing situation. No matter how battle-hardened and powered-up the kids have gotten, they are no where near Gai's or Kakashi's strength and they don't have the necessary experience to handle themselves in such a situation. Having 3 others who are weaker, and less experienced, than yourself is definitely a hinderence in a fight (only ways i can see to counter it is to either attack hard and hope to have one of ur comrades see a weakness, or sacrifice someone). Now Gai and Kakashi have to fight as hard as they can AND make sure nothing bad happens to their respective teams. Already 3 of Gai's members are caught in the water-binding justu so that puts a time constraint and a rescue-mission constraint on his fight. Naruto's been caught in some genjustu and someone will have to snap him out of it (i don't remember him being able to "release" a genjustu - may be part of his growth we will see in the next ep tho). As much as Naruto's enthusiam is his best asset in this series, it would also be his greatest weakness if any of this were even semi-real. As many famous people of our time has said, "you gotta know when to quit."
Just for once i'd like to see someone die for being foolhardy. All this enthusiasm in anime has really gotten on my nerves lately. We need more shikamaru's (now HE knows when to quit!)
Anime trivia: what series did the name "inoshikocho" appear on before naruto (don't search for it a-holes! if u don't know then u don't know)? <--i only know of one series if u know another kudos to u!
