They only do that to reset the defensive line it rarely happens on a 7 tackle set from a kick going dead. Some teams are even too scared to kick a grubber because of giving away a 20 tap I can’t see them regularly taking pot shots from 40 out.
Sorry you've misunderstood my point. Teams give away a "6 again penalty" to reset their defence (not talking about giving away a penalty on a 7 tackle set).
It's the equivalent of a 7 tackle set though.
Point being teams aren't too concerned about 7 tackle sets.
I can just see the gamble of: 40m out, 5th tackle, nothing on - have a shot at a 2 point drop goal and recycling possession becoming the meta. Absolute worst case scenario is the ball goes dead for a 7 tackle set.
Honestly I'm surprised teams don't go for the 1 point and recycled possession when they're 20m out, straight in front.
