It only takes Kakashi to solo team 7. Im pretty sure Rin could stomp Ms. Useless, and Obito would give Naruto a run for his money IMO (even if he doesn't win).
If Naruto isn't allowed to use the Kyuubi's chakra at all, then Team Minato wins rather easily. No Kyuubi chakra means no Kage Bunshin spam nor Rasengan, which means he's taken down by Obito. Kakashi defeats Sakura no difficulty, and from there they team up to take down Sasuke.
L0l what? Give Naruto the Kyuubi. Obito had the full Kyuubi at age 14 plus an MS he solo's. Young Kakashi would get slaughtered by part 1 Sasuke and Naruto.
