I assume by feeding you mean that the ball isn't put into the middle of the tunnel in the scrum?

But it doesn't say in the rules that it has to. It just says it has to be rolled into the tunnel. Which is what happens.

Erm no it isn't it is put in behind the prop forwards outstretched leg. In effect it is put directly to the second row.

Yes it is, the ball is put into the tunnel. Admittedly it's rolled/thrown directly in a gap between the hooker and props legs but it does go in the tunnel. If it didnt then opposition front rowers wouldn't have a chance of kicking the ball, which does happen sometimes. So there is a brief, albeit virtually impossible, chance of the opposition front row getting at the ball. If the ball didn't go in the tunnel then there wouldn't be that opportunity.

Now don't get me wrong, it's definitely feeding. It's just not actually in contradiction with the rule. And personally I'd go back to contested scrums. Or at least look into it.

I don't think the ref should call out at all. It's up to the players to decide for themselves.

That's a lengthy description of him. A mere four letters would have sufficed.

It was always the case that the ball was "in-play" once it emerged behind the 2nd row's feet.
