Horrible play by the US Team, not just the goalie. (What the heck are you doing, leaving the box? Either hurl that ball down field as far as you can, hopefully to a teammate, or stay in front of your goal!)
Their tactics were predictable, they consistently passed to members who were being two-teamed rather than to the more open players, and took too long to make shots, allowing Belgium defenders to run in to blocking position. If you aren't attacking the goal, why the heck are you even down there?
Very disappointed in their play, and frankly surprised by it.
As for the rest, learn the rules. Video review is not allowed to determine a Red Card, by FIFA rules. Thus, the ref in the US/B&H game violated those rules, and should indeed have been overturned. Secondly, any fair viewing of the incident in real time makes it clear it was a near instantaneous collision by two players trying for the ball and personal balance, not an intentional foul. The decision to review was made before any phone call, by the way.
And yes, I actually was a soccer player (fullback/defender and occasional halfback) in middle school and high school. Won three local championships. My specialty was the slide-tackle, and frankly we needed to see more of those in this game. No, I was never even close to this athletic level, but I understand the game, having played it competitively, and with two really good coaches. And yes, I understand the offsides rule, and despise it even as a defender. It's the equivalent of telling an NFL QB he can't throw the ball to a wide receiver who's broken past the safety. Like heck you can't! If the defender is dumb enough to let a striker get past him, that should be his own d fault for not paying attention.
