Basically what djt said.
Last night they fielded a team that would have squeaked out a win, maybe, vs a team like Costa Rico. It didn't look like the team selection and game plan meshed at all. You have a plan of absorbing and countering, but your forward has no want, or the speed, to chase down long balls... or anything not directly played to his feet or head. When your forward players actually get some semblance of possession, Beckerman was nowhere to be found to help keep the ball, rarely venturing past midfield, afraid to get burnt and when he did get on the ball, he almost always picked out a pass to a player on the wrong team, or out to touch.
The guys like Nagbe and Pulisic most likely wouldn't have won the game, but I think their inclusion in the starting 11 would have been able to give the US a counter-puncher's chance and been able to at least run with Argentina. It wasn't about having the players to match Argentina in possession, it was about choosing a team and having the players to be able to execute a plan to counter a team that was 99% going to carry the play and dominate possession.
Also, Bradley didn't do anything to help the team. The captain looked like a deer in headlights all game. Throwing passes to nowhere and taking way, way, way too long to pick out any pass and ended up getting dispossessed way to easily and often.
