I have recs! Two fics by Domenika Marzione (http://archiveofourown.org/users/domarzione/pseuds/Domenika%20Marzione) that I think fit well with the team theme here:

Freezer Burn (http://archiveofourown.org/works/457359)
Summary: The adventures of Steve Rogers, defrosted soldier, who is missing time but not really all that lost. He’s got a surprisingly broad knowledge of lettuces, a working grasp of modern technology, and may or may not be using both to mess with his teammates and save the world.
This is a Steve POV fic, so a lot of it is about Steve, but it's a very well integrated team fic as well, and I especially enjoyed Natasha and Steve's interactions. Gen action/adventure, very long plotty fic :)

BOHICA (http://archiveofourown.org/works/711557)
Summary: Clint Barton, in transition.
A really neat Clint backstory with great Clint and Natasha interactions.
