If we were playing the US, I would want the best the US could toss at us. I would want to show the US that they are fallible, and if we lose...we lose. If we win though, the US can't say that we won because they couldn't field their best.
Seeing the play in full speed, I feel the Red Card was valid. It doesn't have to be intentional to be a Red Card, but it can be due to a very possible chance of injury. Those spikes were too high, the step on the ankle had too much weight, accident or not, that's bad.
I'd laugh though, if the Balogun plays against Belgium, then the Belgium appeal goes through and they suspend him for a game right before the next one. It would be irony for him to play one but be out for the harder game.
That said, I feel Messi did something very similar and should have gotten a Red Card and gotten a pass. Does that mean Argentina will be tainted if they win again? Ronaldo got a three game suspension, and two of those games are in the same limbo at this point. Does that mean all of Portugal is tainted.
There are others that were pretty bad as well. The problem isn't necessarily the Red Card, but the uneven refs and how biased they seem at times vs. certain teams, both for and against. Argentina has gotten some pretty massive passes from the refs, and it's not just Messi.
If anything, people should be outraged by how much the Refs are ignoring some really bad things Argentina is doing.
On the otherhand, Belgium has not really had a ref in their favor (from what I've seen), I can see why they would be really concerned if it appears refs may favor the other team.
