Irrespective of if they made the correct call or not, was still a pretty dumb thing for knight to do, last play of the half right after a scuffle...just wrapping the player up would've done 

Also a pizz take that the 2 hudds players were penalised more by the map than Knight yet neither even resulted in a penalty 

But are you surprised?

Regarding Knights tackle how do we go from:
A clear and forceful shoulder to the head.
To 
Contact mainly all on the body with secondary and minimal head contact. 


The game is in an absolute state.

Cost us 2 point to add to the point against leigh

The judiciary is a complete lottery, fair enough we stunk the place out with our first half performance but for bloke who has multiple cameras to look at and still get the outcome wrong is just a joke. 
Also I'm sure the video evidence would have come from the same TV coverage so you'd have to ask why two people see two different outcomes. 
He system and those running it need a complete overhaul.
