I was watching London Irish V Harlequins earlier today on ESPN. Harlequins won the match in the dying minutes, by scoring a controversial try. The try was scored by a player, who failed to catch a pass. He did touch the ball with his hands, but the ball went backwards, hit off his leg and went over the try line. He then just fell on the ball with his chest. After a couple of minutes with the TMO, the try was awarded.
My question is, does the player have to have control of the ball when scoring a try? There was downward pressure, but the fact that at no stage, had control of the ball, would mean no try.
