The backline "problem" as unnu call it gave up the least goals (2) of all participants in the just concluded GC tournament.
Is the backline at the level of Barcelona? No! But they are competent enough to compete and succeed in CONCACAF. You got to take the successes you had and build on it, that's how you foster confidence. They were the least scored on team in GC, boast pon dat. I don't want to hear any qualifiers. They gave up 2 goals in the tournament. To those who are always talking about JA needs to learn from the USA this is how they do it. They don't qualify their success, they just boast bout them.
They played against the USA with a f'ed up formation and they gave up only 2 goals. The USA used the same formation and gave up 4 to Mexico.
Every CONCACAF team has weaknesses that are exposed when they play against higher competition. When you are playing in a tournament, against the top teams in the competition the #1 priority should be to cover up your weaknesses and try to get the result needed to move on, not leave your weaknesses exposed in a futile attempt to jump on your opponent like Tappa did against the USA. The game is 90+ minutes, the good teams don't care how good you look in the first 30.
Let's look at the forwards. The only time unnu complain about them is when they miss sitters...but is there more to their play that is hindering the team from a defensive standpoint? They have to be more clinical and forceful in attack against better teams to help out the defense. They are not tracking back and they are not clinical enough to keep defenders and defensive midfielders honest. Against the current JA forwards you only need to be concern about them for the first 20 to 30 minutes and then you can become more adventurous out of your backfield. After 30 minutes it seems there is a big dropoff in confidence, effort, discipline and technique.
