I'm not sure that is what is taught to wingers. If the players inside you slide inside, you need to come inside as well, otherwise you leave a big gap on the inside. Far better to have a try scored near the touchline than further infield, as the kick is harder.

exactly my read of it. They didnt trust Williams (who was pretty good in defence i thought) so all go dragged inside.

Had a look at the highlights on Wigan TV and for the first try that definitely wasn't the case. Goulding actually seemed to have quite a lot of faith in Williams as he stuck to his opposite centre even though Williams' man had got on his outside. Goulding only moved inside at the last split second once it was obvious that Hanbury? was going to get the pass away.
Williams was partly at fault for not putting enough pressure on his own man and allowing him to get the pass away but Goulding was in the correct position and Charnley was far too close.

He did the same thing again in the second half. Wingers often get blamed because they are the last man beaten but on this occasion it was definitely Charnley getting caught ball watching. It's something he needs to improve.

Was there a suspicion of a knock on in the build up to Hanbury's try for Widnes?
I've seen the OS highlights, and it appeared the ball came free before the tackle was completed.
The referee re-started the tackle count, but only after a Widnes player seemed to do so in the background.
Am I wrong? Certainly seemed a knock on in real time on the night.
