Pressure is all very well, but what on earth is he up to?

With the referee on the far side of the scrum, Conor Murray of Munster is to put the ball in.  Lee Dickson of Northampton Saints is right up against Murray and making contact with him. Murray tries to move back so that he can put the ball in but Dickson keeps shoving forward against him till the referee freekicks Murray for delaying the put in.

In fact Dickson could have been penalised for playing Murray while the ball is out of play. The assistant could well have helped. At best, Dickson should have been moved away from Murray.
