Mate it's a penalty every time. 'tackled on suspicion', penalised every day of the week.
I don't agree with the rule, but it is what it is.
The man didn't have the ball.
that’s what makes the non call when Tedesco was grabbed while chasing a kick for a try outrageous! Yeah he broke the tackle attempt but it cost him the try. Seems if you dive you get the call, if kikau just bumped off it would be a no call
