80 min is not the end when in possession

When in possession and it's 80 min it would be good to not kick ball into touch
The flipside of that is if you play on and your opponents scores the winner after 90' because you lost possession its going to be annoying AF. I prefer to rather have the win than have that happen.

It would be nice to have the choice for this but I suspect that would require a rather major change to the game engine in its current form.
I reckon, most of the time the game engine gets it about right, any further moves towards retaining the ball could end up in turn-overs and annoying counter-attacks like qBall suggests.
At least they seem to have fixed the anomaly whereby a player will kick to touch on 80' when clean through for a try and especially when a bonus point may depend on that score!
