Have just watched the AAC (Adam Ashley-Cooper) no try again.
It's extraordinary. He was tackled (knee on the ground) more than 5 metres out. He gets twisted on his back in Turner's tackle and you can see him trying to dig his heels in to get purchase to keep the twist going. When the twist orients him the right way he does a couple of knee crawls still with momentum, to get over the top of Turners body which was then facing east-west.
Momentum may have taken him over the goal line anyway without the knee thrusts, maybe not, but let's forget that and everybody knows you can place the ball to score a try if momentum carries you over the goal line. The problem was Turner's body on the line and AAC (Adam Ashley-Cooper) had nowhere to place the ball.
It must have been the two knee crawls/thrusts to elevate himself over Turner's body that were spotted and I'm sure there is a law somewhere that says you're not allowed to knee crawl, but I'm too lazy to look it up. How the knee work was noticed in real time was also extraordinary.
The players did well. AAC (Adam Ashley-Cooper) did everything he could have to score the try and would have got away with it 4 times out of 5 I reckon. He fended Turner nicely and it took Turner a couple of AAC (Adam Ashley-Cooper) steps before he could counter it but Turner brought him to ground and managed to defend the chalk on the goal line with his body.
Beale looked like a goose at first marking the outside man BKH, but he looked better on second viewing. Because AAC (Adam Ashley-Cooper) was so close to scoring Beale had no room to turn and run back to oppose BKH had AAC (Adam Ashley-Cooper) thrown the pass. Instead he went forward in the gap at just the right time to block the pass and maybe make the intercept.
Had AAC (Adam Ashley-Cooper) just been passive after being tackled and tried to place the ball I don't have any doubt (now) that he would not have scored; there was no spot to place the ball for starters. Not that tackled players are ever passive in such situations in the real world. Nor do defenders release tackled players sliding toward the goal line.
