I can't argue the specifics but I saw one thing in these last two games.
When Panama attacked down their left side, they made life crazy stressed for us.
When Martinique attacked down their left side, they almost always got immediately snuffed.
The difference? Zusi vs Lichaj.
Zusi was horrible. The most disaster-promoting player in the game (if Gonzalez wasn't cleaning his crap up constantly we'd have lost that thing by at least two goals). My amateur view saw Lichaj as the solidest player we had in his game (give Morris credit for the two goals and really good play, and a few others like Gonzalez, who makes better saves than announcers give him credit for, and a surprising Zardes.) In fact Lichaj looked so good (both ends) that I'd REALLY like to see him play out this cup to see if this was a fluke.
If I was starting a team just now, it would be Howard (please God let him be healthy), Cameron and either Brooks or Gonzalez at CBs, Yedlin and either Villafana or Lichaj at outside backs, Bradley and Pulisic for sure, Nagbe probably, Wood and Dempsey, and one other midfielder ........ hmmmmm ..... Johnson? Kljestan? Corona? Arriola? --- can SOMEBODY please show some last third footskill and passing accuracy please?
