EVERY player is in the team to defend or, at least they should be.
Of course you wouldn't put your halves in the middle but, you would expect them to be tackling their opposite number.

On the game itself, with the patched up side that Trinity put out, especially with the late withdrawal of MCB, we never looked like we would have enough to win the game.
Even with a full squad to pick from, this would have been a tough ask but, as we were, it was always a question of how many Saints would win by.
The bookies had Trinity with 20 points start and even that didn't look enough and so it proved.

Saints played well today, especially in the first half but, were never tested.

We were close to that first incident, the player had a knock to the knee and got up on all fours to ease it off. The trainer came on and told him to lie down and it looked as though he indicated a head knock to the touch judge. By that time the tackle was 65 metres away and I assume the touch judge relayed head knock to the ref who decided to stop play. That was what the fans were booing for because it looked as though the officials had been conned as saints were 10 metres from the try line.

The second incident was a straight forward head knock and I dont think the home fans responded as much as the first incident despite the fans seeing it with a bit of suspicion.

Yes you are correct.
I should have said....he's not in the team to tackle. However defend is different.

Isn’t in the team to defend now that’s a classic. That’s why yesterday rocky pulled off 3 or 4 try savers and jowitt did last week cause people aren’t doing their job.

You see I already said I was wrong and changed defend to tackle.
I cannot answer for your eyesight.
