Yep "Avengers" will be their first outing as a full team. They're basically learning to be heroes as well. They're all "rookies" as far as Fury is concerned. Captain Craig is posting as if the Avengers are already established in the Marvel Cinematic Universe which they're not. I remember the gag reel from "X-Men"...Spidey showed up
Well based on TIH
, Hulk has been around for at least 5 years.
Iron Man has been around for over 6 months
Captain America, well, decades
Thor is a timeless deity just appearing
Black Widow and Hawkeye are the "rookies" for this team.
All this film is doing is getting them together. The fact that in the MCU most of them have been out doing heroics, sans Hulk, for some time is what I meant. Spidey is, again, just showing up and this team has it's "rookies'>
