Now you're really clutching at straws. Do you suggest that when we have a free kick 30 yards out, or a corner, we should play the ball back to the goalie so we can start another bit of build-up play? If we have a player who can deliver the ball on a sixpence to whoever is in the box, is that not a perfectly legitimate attacking tactic, and not, as you say, cynical? And it is only part of JWP's game, as has been said above. He is 19 years old, and still learning to play at the level demanded of a Premier League player. It is to the immense credit of the club that he has been given that chance, and I am confident that their faith in him will pay massive dividends when he realises his full potential in a few years' time.
And as for your rugby analogy, it is clear you know little about that game if you think that (a) kicking penalties is a cynical tactic, and (b) Johnny Wilkinson does nothing else. He is a complete fly half, who uses the ball from hand or foot as the situation demands. If James Ward-Prowse becomes half the footballer that Wilkinson is a rugby player, we have indeed got ourselves a diamond.
