The reason Man City got rid of Joe Hart was because of his distribution. Simply stopping the ball going in the net was not enough.I totally agree with your last couple of sentences but it's not the way the game is anymore. Goalkeepers are expected to be as comfortable in possession as the most skilful of playmakers these days. I strongly disagree with this method of coaching as goalkeeping is a specialist position in itself which requires a lot of work to perfect without adding the extra workload of acting as an outfield player when your team is in possession. A goalkeeper is there to stop the ball going in the net, simple as that really.
