Oh yeah, I wonder what that records book that Tsunade was reading would have said about Naruto's team, since that was the only team she didn't look at.

Yeah it should say A-rank missions completed-1 for naruto's team since they did one. I'm pretty sure I remember hearing Kakashi saying that the Zabuza mission was A-rank. Though Sakura doesnt deserve the mission to count for her, since she did absolutely nothing the ENTIRE mission.
