but he wasnt looking at the man and slowed down the man just chose not to follow the ball. So im not being daft im being realistic. No dummy runners inside the 10 meter line sound better?

The dummy runners need to be cleverer when they're that close to the line IMO. If you look at the replay, Roberts was quite shallow in the line because of how close we were. If you take that exact same play back 20 yards, he has more of an angle to work from and more space for the DR to avoid hitting the defender.

but, he didnt hit the defender, the defender just made no attempt and just stood watching the dummy runner run at him, I agree there are obstruction eg when the dummy runners clatters into someone who is actively looking to tackle, but that wasnt. He couldnt have been an effective dummy runner any other way than he was. If he would have looked at the defender and stopped it would not have been effective as it would have been obvious he was a dummy runner instead of looking at the passer with his hands out.
