It's like people haven't seen him play when he cared about being a football player more than his career off the court.
And yes he had a lot more to his game than just free kicks. He was probably the best passer/crosser in the world, he could put the ball wherever he wanted, he was also one of the best long distance shooters not just in free kicks. Just because he wasn't your traditional winger who does flashy dribbles doesn't make him less of a player, if anything makes him more valuable because there are a lot of those and very few like Beckham.
Anyway, he then became e boy, cared more about modelling and publicity then the sport and went to the US to play retirement football. It's kind of easy to forget his young days after that.
