Dest is ready to contribute now. He is no longer just a developmental player. I don't think that he is a starter-level player for the USMNT on defense given his problems in isolation, but he would be an ideal change of pace super-sub to shake up one of the wings. I'd even sub him in at R or L midfield like Klinsmann did with Yedlin against Portugal. A player like Dest can wreak some havoc against a tired defense.
