Quote: rolyanste "but if the ball was knocked out it surely should of been a penalty as there was more than one player involved in the tackle... therefore not a 1 on 1!!'"
I've not watched it back on BBC yet, but to my mind, that was the only way it could've been a drop-out; if the ball was knocked out, backwards, by a Wigan player in a 1-on-1 tackle, and then grounded in-goal by Tommy.
My recollection of it is that there was more than one Wigan man in the tackle when the ball came loose, so I too was baffled by the GLDO decision from the video ref, and still am after reading people's interpretations here.
