Barton

Coulson took a chance on Clint Barton, and Clint would very much like to live up to that, but that doesn't mean he does things by the book. He screws up (sometimes on purpose) all the time, he blows up alien tech instead of bringing it back for R&D to study, and he tends to bring home stray Russian assasins. In his defense, he only did that last one once.
