before i start please no sasuke fanboys should coment without reasonable reason
if sasuke was to attack konoha and naruto was dead... Kakashi, Gai, Yamato, chouji, shika, sai, sakura, Neji ,Lee, shino and kiba were to fight him, wud they suceed?
Let's break it up, who are the front-line fighters? Kakashi and Gai, of course are going to be point. Let's say Lee, Neji, Choji and Kiba are up front too. Yamato, Shino and Shikamaru are mid-range support. Sai could be either front or mid-range, depending on what the team needs. Sakura is rear guard/medical and stays in the back to support.
Lee and Gai (and maybe Sai and Neji) will do well if Sasuke is undefended, but none of them really have the ability to break through susanoo. Plus, Gai has a nasty habit of opening gates too early in the battle and going for a 1-hit kill. If he misses or fails, he could be out of the battle permanently. Kakashi is going to go in with a lightning clone to start, most likely, and will waste a lot of chakra on that strategy. If he tries to use Kamui for defense (like protecting against Susanoo's arrows, etc) he could blow through all his chakra very quick.
Choji can get bigger, but he'll just become a bigger target for amaterasu. Maybe one or two good punches on Susanoo, but he won't be much help. Shikamaru has his shadow skills and good strategy, but he doesn't have the kind of power you would need to break through a susanoo defense. If he's standing still using his shadow techniques, he's a sitting duck for susanoo arrows and amaterasu. Remember, Sasuke can use these things even if he's standing still or immobilized.
It's a tough battle, but Sasuke is a very well-rounded fighter and many of the opponents are 1-dimensional. Gai and Lee have no ninjutsu. Kakashi has too little chakra and techniques (chidori, kamui) that eat too much of it. Yamato's wood techniques are probably the most valuable part, but he's only going to be good in a well-coordinated team, especially if he can stay out of Amaterasu's line of sight. Sakura is going to have her hands full healing the front-line fighters (and maybe countering poisons, if Sasuke is using those)
In the end, I think Sasuke wins. He has too much power up front, and his opponents aren't going to be able to avoid his offense and break through his defense at the same time.
