Thoughts on this? Lead runner is tackled by the defender. He makes a tackle with a player without the ball. The defender makes a strange and illegal decision to tackle, but in the big picture it's a great decision because the refs rule obstruction. This was not a case of the defender being blocked by the lead runner. That's three tries in three weeks where dodgy calls on obstruction where defenders are intentionally hitting players without the ball, or hitting the ref to overturn tries.
