I feel like everyone has been overly harsh on Carlos. The last few games he played he was brilliant and in this latter half of this season he has often been the one dragging us through.
Think he had problems settling in; his family wasn't here, the weather was shocking and he just came back from a league that treated him like crap. Didn't help the team wasn't playing well, either.
Sure, he's made some comments in the media that he shouldn't have (though I'd argue that perhaps Ernie didn't talk to him as much as he should have after that game and perhaps didn't explain the reason for leaving him out properly) but the most recent ones seem to be born more out of a desperation to play even when injured; and I don't think that desire is a bad thing.
