I think the US has the back line figured out. Miazga, Long, and Brooks are a solid rotation of CB's. Cannon looks like one to watch in the future. LB is really the only question mark. Ream wasn't terrible but you could tell he was a CB trying to masquerade as a wing back. The wings actually appear to be in good shape. Pulisic should actually play his natural position. Arriola has a lot of raw talent, just needs to figure it out. I'm not sold that Sargent is the guy to play as the #9, but we'll see. Midfield is a mixed bag. Bradley retiring from international play will be addition by subtraction whenever it happens.
