I went to the LA Galaxy-Earthquakes game last night in Oakland. I'd never seen an MLS game, and they had a good crowd, apparently the largest crowd in MLS history.
Beckham was quite good, probably the best player on the field. In person, you can see that he generally plays far wider on the field than anyone else. Everyone else would be bunched up on one side and he would be all alone on the other waiting for the ball. I would imagine that's because he's used to somewhat better teammates. For fifteen years he played at the best clubs in England and Spain, with better teammates, who are somewhat more used to using the entire field.
He's still an extremely accurate passer. He's got great vision and can pick out any of his teammates on the field, not just where they are, but where they will be when his pass gets to them.
Like the article said, he isn't very physical these days, or at least he wasn't last night. Maybe after all his ankle trouble last year, he made a decision to try to avoid getting hurt.
