It was 1-on-1 so a scrum, not a penalty, but otherwise, yep, agreed. And yeah. as jonh says, the Crosby penalty wrondly awarded immediately after was also crucial.

the tackle was completed though so that would make it interference wouldnt it?

Possibly, but from that part of the field it makes no difference really, we wouldn't have kicked for goal.

Farrel should of kept hold off the ball. Simples.

I seem to remember a lot of whinging when Sam had his arm trapped and doing similar a few years back
