So much we could penalise at this scrum, but would Joe Public then be calling on the ref to not be strict since scrums are messy enough?
#1 - Wales have given up pushing straight and start to wheel. Take Browner's clip and have a look at what the Welsh #5 and #6 do. Not only forcing the scrum to disintegrate but forming a very effective block for the English blindside flanker. But then again, Haskell missed the tackle by going too high.
#2 - the Faletau digging. He's not even the hindmost man, there are 2 behind him thanks to Englands effective (and legal) scrummaging.
#3 - the Faletau digging. He's got a knee on the ground, ergo not on his feet. Check out 20.9(a)
"A player must not intentionally fall or kneel in a scrum"
#4 - the Faletau digging. The ball is nowhere near his feet, he really has to grab from a distance and, as others have pointed out, had to drop his left hand bind in order to be able to reach in far enough.
#5 - Ben Youngs. Yes, starts from an offside position and carries towards the ball, but doesn't get anywhere near touching anyone with the ball. Material?
My conclusion: the lack of penalising Wales for any of 4 PK infringements was very material: Wales got 7 points. England's only infringement wasn't material.
But there was some awful tackling attempts between Faletau finally getting the ball and the try being scored.
