Quote: Him " However in this case the long shot from behind was shown to Silverwood and he even commented on the shot that showed the ball above the ground at all times. '"
That's not correct. Silverwood saw two angles - one in front, and one from behind. The one from behind the play he saw was obscured slightly by a Salford player (Lui I think). The longer shot that clearly, unequivocally shows the ball not hitting the ground only seemed to emerge about 20mins later - it wasn't shown to Silverwood in the decision making.
Not to defend Silverwood. He knows there is a camera there (there always is), he should have asked for that angle before making his decision.
